## Abstract This paper describes a new aperture‐coupled microstrip patch antenna with H‐shaped slots for dual‐band and dual‐polarized operations. Two orthogonal modes are excited in a single long rectangular patch to achieve the two resonant frequencies with a separation of more than 2:1. By using
## Abstract Two new configurations of patch antennas are introduced, which provide dual‐band and dual‐polarization operations. The two patches have a square and cross shape, and are printed on a single layer; the dual‐frequency and the dual‐polarization behavior is obtained by means of four narrow
## Abstract In this article, a novel dual‐band hybrid coupler is designed by adopting improved simplified composite right‐/left‐handed (ISCRLH) transmission line (TL) stubs.An ISCRLH TL stub is composed of two ISCRLH TL unit cells with input and output uniform TL sections at the terminals, which ca
## Abstract A compact wideband circularly polarized rectangular dielectric resonator antenna (DRA) with dual underlaid hybrid couplers is investigated for the first time.As no extra footprint is needed for the couplers, the proposed antenna is very compact. The dual hybrid couplers are connected to
