7 dBi and axial ratio lower than 1 dB in the azimuth plane
at the center frequency.
4: shows the simulated Azimuth Plane
Pattern of proposed multiband antenna.
3(b) shows the simulated RHCP radiation pattern and the cross-polarization (LHCP) for two orthogonal planes, the azimuth plane
and the elevation plane.
Next, the simulated realized gain patterns in the azimuth plane
are obtained from 1.
Figure 3 shows the radiation patterns of the antenna in the common mode in the azimuth plane
(for vertical polarization).
The measured results show generally good omni directional radiation in the azimuth plane
(the x-y plane) especially in the lower bands that is the 2.
L-, S- and C-band antennas are available with omni-directional coverage in the azimuth plane
Three-stage of 2-way dividers have been grouped to shape an 8-way power divider over SIW, as Figure 4 shows, to feed the array for the azimuth plane
The radiation pattern bandwidth of the high-gain omnidirectional (in the azimuth plane
) antennas, which are defined as the frequency range over which the gain at the azimuth plane
, is within 1 dB of its maximum gain.
s]([theta]) indicates the relative distance of the satellite to any point of the illuminated earth surface in any cut of the azimuth plane
This antenna has a peak gain of +4 dBiL and omni-directional coverage in the azimuth plane
