Description (one paragraph)

• Ultra Wide Band (UWB) radio is a developing technology with smart features useful for wireless communications, networking, radar processing, imaging and positioning. Ultra wide band can be defined a very short range carrier communications technology which basically transmits information in the form of short pulses.

• FCC released in 2002, ultra wide band antenna operates the frequency range (3.1 – 10.6 GHz).

Introduction

Antenna sizes became one of the greatest challenges in downsizing

wireless modules

Challenges are also due to their integration with boards containing

many electronic devices.

Social demand has resulted developments and manufacturing of

modern wireless technologies such as WiMax,Wi-Fi,3G/4G/5G

All of these wireless module, antennas became the front-end of the

integrated electronic modules.

ultra wide band (UWB) antenna has been done in different geometry

in patch antenna with different Slot.

Problem Statement To integrate many services on today’s wireless technologies we need to

have Ultra Wide Band (UWB) antenna.

The design of band notched antenna for ultra wide band applications

has been done in different geometry in order to achieve ultra

wideband, but the problem is the achievement of compactness of the

antenna and better gain.

Proposing a micro-strip patch antenna with innovative design which

allow it to function in an Ultra Wideband Frequency with it Is range

from 3.1 to 10.6 GHz with a better gain.

Objectives

1. To design microstrip patch antenna for UWB applications which included band rejection capability.

2. To perform and analyze the result by simulating using Computer Simulation Technology software (CST).

3. To analyze performance of the designed antennas and fabricate the structure of the antenna.

Methodology

Expected

The expected outcomes of this research which will hopefully be attained by the

end of the research deadline are :

I. A Band notched antenna for Ultra wide band applications with enhanced

efficiency compared to the conventional designs of Ultra Wide band (UWB)

applications.

II. It is also expected to gain knowledge in the field of microstrip patch antenna

structure with ultra wide band applications, patch antenna with notched filter

antenna analysis, synthesis, and fabrication

III. publishing article(s) in revered international or local journals and thesis.

Expected Simulation results
