Ultra-wideband Full-metal Planar Array Antenna with a Combination of Ridge Gap Waveguide and E-plane Groove Gap Waveguide
Artikel i vetenskaplig tidskrift, 2022

An ultra-wideband (UWB) full-metal planar array antenna based on a combination of ridge gap waveguide (RGW) and E-plane groove gap waveguide (E-GGW) is presented for millimeter-wave (mmWave) applications. First, the radiation element of a double-step double-ridged slot structure is proposed and designed. With removing the vertical walls of the cavity in the H-plane, the impedance matching characteristics presents a UWB bandwidth of 53%. Second, a UWB double-layer feeding network is achieved by combining RGWs and double-side-pin E-GGWs for the radiation elements. Finally, an 8 × 8 full-metal planar array antenna with the presented elements and network is designed, prototyped and measured. The measured results agree well with the simulated results. The proposed antenna provides an impedance matching bandwidth (|S11| < -10 dB) of 46.8% from 18.8 to 30.3 GHz. The maximum gain is 27.7 dBi at 27 GHz and a stable gain of 26 ± 1.7 dBi is obtained over the operation band.
