Dual-Polarized Multi-Beam Fixed-Frequency Beam Scanning Leaky-Wave Antenna
A fixed-frequency beam-scanning leaky-wave antenna (LWA) array with three switchable dual-polarized beams is proposed and experimentally demonstrated. The proposed LWA array consists of three groups of spoof surface plasmon polaritons (SPPs) LWAs with ...

A Broadband Multi-Beam Dual-Circularly Polarized Reflect-Array for Ka-Band Application
In this paper, we proposed a multi-beam dual-circularly polarized (dual-CP) reflect-array (RA) antenna for Ka-band application. Two reflection beams fed by the right-handed (RH) CP horn point to $\theta _{\mathrm {R}}=3.5^{\circ }$ and $\theta _ ...
