Design of a double layer cavity backed slot array antenna in gap waveguide technology
Paper in proceeding, 2017
In this paper a double layer cavity backed slot array antenna at K band is presented. The slot antenna is built using ridge gap waveguide feed network and gap waveguide cavity layer. These antenna blocks are manufactured without the requirements of electrical contact between the metal plates The corporate-feed network is realized by a texture of pins and a guiding ridge in the bottom plate. The 4×4 slot array antenna has been fabricated and measured. The measured reflection coefficient remains below -11dB with reasonably good radiation patterns over the band of interest from 18.2 GHz to 21.2 GHz.
