A Circularly Polarized Annular-ring Patch Antenna with a 2010-10-10 · a circularly polarized annular-ring patch antenna embedded in a particular EBG structure and with an unequal cross-slot in the ground plane is studied and presented. This recently proposed annular-ring antenna structure has been shown to be significantly smaller than conventional annular-ring patch antennas, even on standard groundplanes [10]. Design and Analysis of Circular Ring Microstrip Antenna

Abstract|A new CPW-fed dual-band circularly-polarized(CP) annular slot antenna with two perturbation strips is proposed. The structure of the annular slot, along with two concentric annular-ring patches, can achieve dual-band input impedance matching. And circular polarization at the operation bands can be achieved by using

A broadband circularly polarized antenna of square-ring ... Examples of RFID-reader antennas include the patch antenna fed by a Wilkinson power divider and the annular-ring slot antenna with a slot-line feed . However, these antennas are too large, and some single-feed single-element patch antennas usually have a narrow circular-polarized (CP) bandwidth , , , .

(August 2008) Shih-Hsun Hsu, B.S., National Cheng Kung University; M.S., University of Wisconsin-Madison Chair of Advisory Committee: Dr. Kai Chang The reflectarray antenna has been considered as a suitable candidate to replace the Shorted Annular Slot Antenna (ASA) Matched at Three 2005-1-20 · shorted Annular Slot Antenna (ASA) proposed in this paper operates in three different frequencies with the central frequency at 5.8 GHz. It is fabricated on cheap material and is a compact design suitable for integrating in mobile devices. The annular slot antenna on dielectric material has been described explicitly in [1]. Design of Stacked Microstrip Dual-band Circular Polarized 2012-8-3 · A dual-band CP antenna using single layer patch has been reported in [4], [5]. In [4], an antenna consists of a circular patch and a narrow annular ring is designed. This antenna achieves its CP operation by an equal cross slot embedded on the circular patch. The design of antenna in [5] consists of a small circular patch surrounded by two WIDEBAND CIRCULARLY POLARIZED UHF RFID READER …
