2. Introduction

The proposed PNF is a near field antenna test range (over all dimension of PNF chamber L x

W x H: 12.65m x 10m x 11.5m), operational frequency ranges 1.0 GHz to 40.0 GHz for

characterizing various antenna system for GEOSAT, Remote Sensing, Navigation and Ground

Applications programs of ISRO.

Proposed PNF RF measurement setup and positioning system are equally important for

accurate and precise characterization of antenna systems. It will be configured for

characterizing antenna radiation pattern measurement.

Proposed PNF Positioning system should include 4-axis T-Scanner (X-Y-Z-Roll) and 4-axis

DUT positioner (Roll / Elevation / Azimuth / Linear Slide) with controllers. These positioning

systems will be used to support and position test devices, antennas, model towers, etc. for

antenna pattern measurements.

Figure-1: Proposed PNF System

3. Technical Specifications

Proposed PNF positioning system are divided into two type of positioners –

1. 4-axis T-scanner 2. 4-axis DUT positioner

1. 4-axis T-Scanner - The proposed T-Scanner will be fast and ultra-precise scanner with the motor drive, position feedback sensor and limit switch technologies. The selection

of motor drives, encoder and limit switches are pre-defined in detail under list of

deliverables. It is to be required to drive the scanner and get its position feedback on

available multi-axis (upto 4-axis simultaneous controller) 4164 sequential controller

with built in PCU. In addition, we have to ensure its local mode operation through

available local control units and integration of available emergency stop unit for safety

purpose.

The scanner axes configurations and proposed physical dimensions are given below –

X-axis ≤ 11000 mm ≤ 1500 mm ≤ 300 mm 9.0 m

Y-axis ≤ 1350 mm ≤ 1350 mm ≤ 7500 mm 6.0 m

Z-axis ≤ 350 mm ≤ 200 mm ≤ 200 mm 0.25 m

Roll-axis ≤ 280 mm ≤ 140 mm ≤ 220 mm 360deg

The T-scanner will be composed of an X-axis linear slide and a moving tower for the

Y-axis. The linear slide will be constructed by modular sections. These modules will


7

be fixed to the RCC foundation and levelled as one integral track. The Linear-Z travel

axis will move over Y-axis and Transmit probe will be mounted on roll positioner.

We recommend specifically designed T-scanner for medium-duty use, with rugged and

simple construction to ensure high reliability and trouble-free operation. Thermal

switch and Tacho will be required as standard features for drive system.

Special attention will be required during selection of rack and pinions to ensure high

degree of precision for longer life with low backlash. The Y-axis and Z-axis should

have a counter balance mechanism to eliminate backlash and protect the measurement

probe in the events like power failure.

switch technologies. The selection of motor drives, encoder and limit switches are pre-

defined in detail under list of deliverables. It is to be required to drive the scanner and

get its position feedback on available multi-axis (upto 4-axis simultaneous controller)

4164 sequential controller with built in PCU. In addition, we have to ensure its local

mode operation through available local control unit and integration of available

emergency stop unit for safety purpose.

4. System Description

The system referred here will be utilize the Planar Near-Field antenna measurement

technique based on probing mechanical scanning system consists of an inverted T-type

high-accuracy planar vertical X-Y-Z Scanner that moves an RF probe to sample the

electromagnetic field at a plane in front of the DUT. The scanner’s mechanical system will

also allow the Probe to rotate, thus providing automation to acquire the intended (Co) and

orthogonal to intended (Cross) polarization components. In addition, Z-axis will provide

the shifting of probe in Z direction to adjust the plane of the measurement.

The RTC provides the synchronization of the entire data acquisition sequence and

Microwave Data Acquisition and analysis Software to controls and reads positions of all

the motorized scanning axes with the help of an integrated 4164 motion controller and

power control unit, which communicates with the DUT and Probe T-scanner (X, Y, Z, and

Roll axes). Figure-13 shows the proposed test setup of PNF Range.

1.0 Introduction

The proposed PNF is a near field antenna test range (over

all dimension of PNF chamber L x W x H: 12.65m x 10m

x 11.5m), operational frequency ranges 1.0 GHz to 40.0

GHz for characterizing various antenna system for

GEOSAT, Remote Sensing, Navigation and Ground

Applications programs of ISRO.

Proposed PNF RF measurement setup and positioning

system are equally important for accurate and precise

characterization of antenna systems. It will be configured

for characterizing antenna radiation pattern measurement.

Proposed PNF Positioning system should include 4-axis T-

Scanner (X-Y-Z-Roll) and 4-axis DUT positioner (Roll /

Elevation / Azimuth / Linear Slide) with controllers. These

positioning systems will be used to support and position

test devices, antennas, model towers, etc. for antenna

pattern measurements.

4.0 Technical details related to T-scanner

4-axis T-Scanner - The proposed T-Scanner will be fast

and ultra-precise scanner with the motor drive, position

feedback sensor and limit switch technologies. The

selection of motor drives, encoder and limit switches are

pre-defined in detail under list of deliverables. It is to be

required to drive the scanner and get its position feedback

on available multi-axis (upto 4-axis simultaneous

controller) 4164 sequential controller with built in PCU. In

addition, we have to ensure its local mode operation

through available local control units and integration of

available emergency stop unit for safety purpose.

The scanner axes configurations and proposed physical

dimensions are given below –

X-axis ≤ 11000 ≤ 1500 ≤ 300 9.0 m Y-axis ≤ 1350 ≤ 1350 ≤ 7500 6.0 m Z-axis ≤ 350 ≤ 200 ≤ 200 0.25 m

Roll-axis ≤ 280 ≤ 140 ≤ 220 361 deg

The T-scanner will be composed of an X-axis linear slide

and a moving tower for the Y-axis. The linear slide will be

constructed by modular sections. These modules will be

fixed to the RCC foundation and levelled as one integral

track. The Linear-Z travel axis will move over Y-axis and

Transmit probe will be mounted on roll positioner.

We recommend specifically designed T-scanner for

medium-duty use, with rugged and simple construction to

ensure high reliability and trouble-free operation. Thermal

switch and Tacho will be required as standard features for

drive system.

Special attention will be required during selection of rack

and pinions to ensure high degree of precision for longer

life with low backlash. The Y-axis and Z-axis should have

a counter balance mechanism to eliminate backlash and

protect the measurement probe in the events like power

failure.

6.0 System Description

The system referred here will be utilize the Planar Near-

Field antenna measurement technique based on probing

mechanical scanning system consists of an inverted T-type

high-accuracy planar vertical X-Y-Z Scanner that moves an

RF probe to sample the electromagnetic field at a plane in

front of the DUT. The scanner’s mechanical system will

also allow the Probe to rotate, thus providing automation to

acquire the intended (Co) and orthogonal to intended

(Cross) polarization components. In addition, Z-axis will

provide the shifting of probe in Z direction to adjust the

plane of the measurement.

The RTC provides the synchronization of the entire data

acquisition sequence and Microwave Data Acquisition and

analysis Software to controls and reads positions of all the

motorized scanning axes with the help of an integrated

4164 motion controller and power control unit, which

communicates with the DUT and Probe T-scanner (X, Y,

Z, and Roll axes). Figure-13 shows the proposed test setup

of PNF Range.
