- This letter presents the design and the fabrication of a 32 x 32-element high-gain corporate-fed slot array antenna in the E-band. First of all, a 2 x 2 cavity-backed slots subarray is designed. Second, the subarray is extended to the whole array antenna by T-junction power dividers. In addition, a vertical transition from WR-12 to distribution network is also designed in order to excite the array antenna. For massive production in industry, the proposed antenna is manufactured in reality by utilizing chemical-plated polyetherimide. Then, the fabricated parts have been adjoined together by two thin layers of isotropic conductive adhesive. Finally, the fabricated antenna shows an impedance bandwidth of 20% with input reflection coefficient better than -12 dB and the aperture efficiency mostly larger than 60% with about 37 dBi realized gain between 71 and 86 GHz.

- 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.
