Abstract

In this paper we present a one-dimensional monopulse antenna in groove gap waveguide (GGW) technology. A riblet coupler with a 90 degree delay line is designed to achieve proper sum and difference performances of the monopulse comparator. The outputs of designed 180 degree hybrid are connected to 4 way power dividers in order to feed the radiating elements. A 1×8 array of slots is used as the radiating section of the proposed antenna. A sample antenna is designed and simulated for operation at Ku band. Simulation results show that the return loss is more than 10 dB around 14GHz center frequency and the proper sum and difference performances.
