Ultra-High Efficiency Antennas

• Founded: 2001

•Management:Extensive experience from supplier and operator environment: Ericsson, Nokia, Lucent, MSI, Allgon

• Location: Stockholm, Sweden

COMPANY- Background

• To produce Erlangs, MB/s and km2 of coverage to

lowest possible production cost!

• To sell Erlangs and MB/s, at a prize that maximizes

profit.

To build sites is not a mission!

OPERATORS MISSION

ANTENNA – Conventional Feed network

To the left, three of the major vendors

can be seen.

The one to the right has a combination

of circuit board and coaxial cables.

But all three suffers from a loss of

one to two dB per meter of antenna

length.

Which means 2-4 dB of loss for a 2

meter 18 dBi antenna!

Towards the horizon If we assume that ”same

tilt” means a tilt with the

same radiation towards the

horizon. We will set the two

antennas at a tilt at or near

their VBW

This will give us for the 21 dBi antenna:

Tilt 4 degrees, upper -3 dB (18 dBi) at -2 degrees and lower -3 dB at -6

degrees

For the 18 dBi antenna:

Tilt 7 degrees, upper -3 dB (15 dBi) at -3,5 degrees and lower at -10,5 degrees

The big picture!

• Pointing 75% further out

• Giving 3-4 dB higher gain in bore sight

• Delivering 1 - 3 dB more radiated power

In total, significantly better

performance in the entire cell.
