Circularly-polarized annular-ring patch antennas with size reduction

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. 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 ... Circularly polarized co-designed filtering annular slot ... 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 with a microstripline bandpass filter (BPF) to enhance out-of-CP-band suppression.

Circularly-polarized annular-ring patch antennas with size reduction

Annular Slot Loaded High-Impedance Ground Plane - ECE/CIS A conventional slot ring without a grounded dielectric will radiate at a frequency determined by the guided wavelength of the slot. That is, an annular slot antenna will radiate its fundamental mode at a slot radius of [2] Annular Slot Loaded High-Impedance Ground Plane A Compact Annular Ring Microstrip Antenna for WSN Applications A compact annular ring microstrip antenna was proposed for a wireless sensor network (WSN) application in the 2.4 GHz band. In this paper the major considerations of the conformal antenna design were the compact size and the impact on antenna's performance of a steel installation base. Printed ring slot antenna for circular polarization - IEEE Abstract: 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 asymmetry in the ring slot structure and feeding the ring slot using a microstrip line at 45/spl deg/ from the introduced asymmetry.
