Abstract:A dual-band dual circularly polarized (CP) patch antenna is proposed with low profile and small frequency ratio in this letter, which consists of a square patch, coupling lines, and a dual-feed network with dispersive delay line. Noticing that this antenna is fabricated on a single-layer substrate, thus acquiring low-profile performance. As for the coupling scheme, the bandwidth of impedance matching is increased to achieve dual-band radiation performance. On the premise that two orthogonal signals, which tran… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
