Abstract

This paper presents a high gain 4×4 slot antenna array designed to operate in Ka-band (in this case 35-40 GHz) as a soil moisture radiometer. Simulation result with measurement are presented for the slot antenna array. The main hind sight of a
slot antenna is the radiated back lobe which can be improved using a reflector. A complementary patch array reflector is used to suppress back lobe radiation in simulation. Comparison of simulation as well as measurement with and without backreflectors are discussed. Radiation patterns and different side lobe levels for different frequencies are justified.
