Summary: The novel ultrawideband dual-polarized H-plane horn antenna with a Vivaldi array combines an all-metal shared aperture structure, using a rectangular waveguide for vertically polarized H-plane horn antenna and slot line for horizontally polarized Vivaldi antenna array. The Vivaldi slot significantly increases the HP bandwidth without disturbing the VP radiation pattern. The antenna has a measured -10 dB impedance bandwidth of 103% for HP mode and 77.5% for VP mode, with a peak gain of 13.0 dBi for HP and 14.3 dBi for VP.

Summary: A dual-polarized antenna based on a substrate-integrated waveguide (SIW) horn antenna and Vivaldi antenna is proposed, achieving both horizontal and vertical polarization. A dielectric lens is designed for impedance matching and directivity enhancement. The measured results show a 20.04-25.5 GHz overlapped dual-polarized impedance bandwidth and the maximum gains of 5.2 dBi and 8.2 dBi for the HP and VP, respectively. With good isolation of 35 dB, this proposed antenna meets the demand for simultaneous transmission and reception of signals in two polarization directions for wireless communication.
