Design of a Horizontally Polarized Slotted Waveguide Antenna Element for Airborne Ka-PolInSAR System
2019
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, which is an extension of the existing airborne
DLR F-SAR sensor [1] and it will be used to investigate
polarimetric interferometric Synthetic Aperture Radar
applications. Based on theoretical analysis an appropriate design
has been developed regarding to the electrical and mechanical
system specifications. The simulation results show a good
fulfillment of the requirements. The measurement results of an 8-
slot prototype of the antenna validate used technology and the
simulation model.
