Current and next-generations of communication systems demand for high-data rates devices with enhanced coverage and compact dimensions. We present here a dual-polarized, differentially fed, metasurface leaky-wave antenna for dual-polarized and full-duplex applications. The design is based on a slotted substrate-integrated waveguide designed to excite two orthogonal polarizations and to provide differential feeding. The antenna is constituted by a partially reflective surface placed on the top of a dielectric substrate and it operates around 24 GHz, providing satisfactory impedance matching, isolation greater than 50 dB, and maximum realized gain of the order of 18 dBi.

Abstract
Current and next-generations of communication systems demand for high-data rates devices with enhanced coverage and compact dimensions. We present here a dual-polarized, differentially fed, metasurface leaky-wave antenna for dual-polarized and full-duplex applications. The design is based on a slotted substrate-integrated waveguide designed to excite two orthogonal polarizations and to provide differential feeding. The antenna is constituted by a partially reflective surface placed on the top of a dielectric substrate and it operates around 24 GHz, providing satisfactory impedance matching, isolation greater than 50 dB, and maximum realized gain of the order of 18 dBi.| File | Dimensione | Formato | |
