In this paper, a compact circularly polarized co-designed filtering annular slot antenna (ASA) is proposed. The antenna comprises a distributed capacitor-loaded annular slot radiator to produce circular polarization (CP) radiation, which is seamlessly integrated A Novel Concentric Annular-Ring Slot Dual-Band Circularly ... In this paper, a novel concentric annular-ring slot dual-band CP microstrip antenna that operates at ISM band (2.45 GHz) and 5G band (3.5 GHz) is proposed and investigated. The antenna is a kind of single-layer slot antenna. There are two concentric ring slots of INTEGRATED COMPACT CIRCULAR POLARIZATION ANNULAR RING SLOT ... addition, because of the compact size of the ring and ring slot antenna, it has been widely used for difierent antenna designs such as UWB [10] and dual band applications [11{13]. In this paper, annular ring slot antenna is integrated with the hybrid patch DUAL-BAND BEAM SCANNING REFLECTARRAYS AND NOVEL WIDEBAND AND ...
