Omni-Directional Antennas 1.7-1.9GHz

1.7 GHz - 1.9 GHz Omni-Directional Antennas

Omnidirectional Antenna

When designing these antennas, great care was taken with the radiation patterns, both in the 360 degree direction and in the elevation plane. (See patterns below).

Many competitive omni-directional antennas considerably over claim their gain figures. Very often the radiation pattern is not smoothly omni but has shallow nulls in it. In the elevation direction a feature known as "frequency scan" occurs. This is where different frequencies reach maximum gain at different elevation angles. From the subscribers point of view this shows itself by having different gain figures at one end of the band as against the other. All this results in poor system performance and high bit error rates.
