چکیده
In this paper, a dual-polarized antenna based on substrate-integrated waveguide (SIW) horn and Vivaldi is proposed. The horizontal polarization (HP) achieved by using the H-plane SIW antenna, while vertical (VP) realized typical etched surface of antenna. front aperture, dielectric lens designed to optimize impedance matching enhance directivity. Different feeding structures two polarizations are used isolation between ports. measured results demonstrate 20.04–25.5 GHz (23.97%) overlapped bandwidth, maximum gains HP VP 5.2 dBi 8.2 dBi, respectively. A good 35 dB within operating band realized. proposed meets demand transmit receive signals in directions simultaneously for wireless communication well.
