Design of a Horizontally Polarized Slotted Waveguide Antenna Element for Airborne Ka-PolInSAR System
This paper presents the design of a horizontally polarized slotted waveguide antenna single element with low cross-pol level, low side lobe level and high gain. This antenna will be used for the DLR airborne dual polarized Ka-Band PolInSAR system, wh
