The design of a microstrip-fed annular-ring slot antenna (ARSA) with circular polarization (CP) radiation is initially studied. To obtain CP radiation with broad 3-dB axial ratio (AR) bandwidth Printed ring slot antenna for circular polarization A new design of a microstrip-line-fed circularly polarized printed ring slot antenna is proposed. Circular polarization (CP) radiation of the proposed design is achieved by introducing proper 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 different size on the ground to generate dual-band radiation. Design of aperture-coupled annular-ring microstrip Abstract: The design of an aperture-coupled annular-ring microstrip antenna for circular polarization (CP) is presented. The CP radiation of the annular-ring microstrip antenna is achieved by a series microstrip-line-feed configuration through the coupling of a ring slot in the ground plane.
