Optimizing Cx Polarization Pattern for Patch Antennas
Optimizing Cx Polarization Pattern for Patch Antennas
(OP)
Dear All,
does anybody know ways to increase the cross polarization supression of a single microstrip patch antenna?
The following technics are known:
1. Feeding the patch with two feeds. One feed has 180° phaseshift.
2. Bending the corner of the patch.

How much isolation do you need? Who picked a patch? I assume it's mechanically constrained.
Crossed notched antenna can get 40 dB over 3:1 bandwidth.
We get 50-70 dB regularly (tunable to 80 dB I would surmise) with a dual pole horn across more than 2:1 bandwidth.

how would you feed the patch with 4 feeds for one polarization? At present I use 2 feeds (180° out of phase)for the V-polarization, like that:
