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.

Dear Everybody,
does anyone know how to stablize a 7 GHz up-converter output signal?
The up-conversion works in two steps. 180MHz is first IF and 570 MHz is the second IF. Now we noticed a level imbalance of around +- 1.5 dB on a temperature range of +-30K.
Design is in MMIC.
The goal is...
Hey everybody,
has somebody of you experience in building LFOV (Limited Field of View) arrays?
My design has a 4x8 patch matrix with lambda/2 spacing.
The patch element has a 3dB beamwidth of around 105°.
Which field of view you would expect by assuming a very clever amplitude and phase...
Dear Experts,
I am designing a patch antenna in X-Band. This patch is a multilayer aperture coupled (H-polarization) and pin coupled (V-polarization) patch antenna which uses distances between the patches and the reflector plane. The patch is designed for good cx-pol suppression in both...
