- In this letter, an end-fire double dipole antenna fed from double-ridge gap waveguides (DRGWG) is proposed and designed for multibeam array application. Two dipoles with different lengths are connected to the extension of the ridges of DRGWG in series. Different resonances can be generated by these two dipoles, which contributes to a wide impedance bandwidth, high gain and stable radiation patterns across the working band. The double dipole antenna is vertically polarized and has a wide H-plane beam width suitable for beam scanning application. To verify the performance of the double dipole antenna, a butler matrix is designed based on ridge gap waveguides (RGWG) to feed a 1*4 double dipole array arranging in H-plane. The maximum gains achieved for Port 1 and Port 2 are 13.94 dBi and 12.68 dBi respectively. Besides, the simulated radiation efficiencies for Port 1 and Port 2 are both above 94%.
