Zhang, "Broadband dual polarized waveguide slotted antenna array," IEEE Proc. Compact X band Synthetic Aperture Radar The SAR antenna is a deployable honeycomb panel antenna with slot array, that can be stowed compactly. RF instruments are on a satellite structure and feed through waveguides. RF signal feeds through a choke flange at a hinge. The current status of the hardware development will be presented. Slotted Waveguide Array The slotted waveguide array is a popular choice for use in radar systems due to its mechanical robustness, compactness and ability to handle high power levels. The impedance and resonant behaviour of an isolated slot depends on its size and placement (position and orientation) along the...

Slotted Waveguide Antenna - Keysight The slotted waveguide has achieved most of its success when used in an omnidirectional role To make the unidirectional antenna radiate over the entire 360 degrees of azimuth, a second set of slots are cut in the back face of the waveguide. When looking straight at the face of the waveguide you will be able to see straight through both slots. Broadband ridged-waveguide slot-antenna array fed by a back ...
