Abstract

Waveguide slot antennas and arrays date back to the forties, but they are still nowadays very popular as high-frequency antennas, mainly for RADAR and communication systems. In this paper we describe the main limitations and drawbacks of waveguide slot arrays configurations, and the possible countermeasures proposed in the literature, focusing on the improved design technique available for high performance planar waveguide slot arrays.
