Wideband High-Efficiency Slot Array Antenna Based on Gap Waveguide Single-Layer Feeding Network
A single-layer, full metal, wideband, and high-efficiency slot array antenna operating in V band [(50 to 75) GHz] is proposed using a single corporate-feeding network based on gap waveguide (GW) technology. Compared with conventional multilayered slot array antenna, the proposed antenna utilizes only one waveguide feeding layer to excite the radiation slots; therefore, the assembly complexity of multilayer waveguide and manufacturing cost is greatly decreased. The proposed 16 × 16 slot array antenna consists of four 64-element smaller array antennas in which all radiation slots are fed by an E-plane groove gap waveguide (EGGW). Power division in each of the 8 × 8 element array antenna is realized by a wideband combined ridge and EGGW power divider. Two wideband E-plane groove gap waveguide T-junctions have been used to connect all four 64-element subarray antennas with proper phase and equal amplitude together to obtain higher gain. The final 16 × 16 slot array antenna has a peak gain of 32 dBi gain and about 36% impedance bandwidth at V band. Also, the full metal antenna array has an average efficiency of 80% over the entire bandwidth of 50 GHz to 72 GHz.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
