- In this letter, a wideband millimeter-wave planar array antenna with a printed ridge gap waveguide (PRGW) feeding network is presented. A planar bowtie antenna fed by the PRGW is employed as the array radiation element which combines the bowtie with an upside-down electromagnetic bandgap (EBG) part by using lamination. Thus, with this new upside-down structure the proposed array antenna achieves a stable, wideband and high-antenna-efficiency performance. A prototype of "8""8" element array is fabricated and measured. The measured results show that the proposed array has an impedance matching bandwidth (S11-10 dB) of 50.3% from 18.6 to 31.1 GHz. The maximum measured gain is 22.1 dBi at 29 GHz, and the total antenna efficiency is above 60% with a bandwidth of 45% from 18.8 to 29.8 GHz.
