Abstract

To meet the required precision and reliability for global positioning systems, a probe‐feed dual‐band circularly polarized (CP) microstrip antenna is proposed.This new microstrip antenna design uses a circular patch that is printed on a two‐layer substrate consisting of an FR4 dielectric layer and a foam layer, and cutting a crossed‐slot and an open ring‐slot in the circular patch. When compared with the conventional dual‐band CP antenna with two patches among substrate materials, not only is the performance of the antenna improved but also its fabrication becomes easier. The simulated and measured results indicate the validity of the design. © 2010 Wiley Periodicals, Inc.

This paper presents a new, compact, dual-frequency design of single-feed circular microstrip antennas with an offset circular slot placed close to the patch boundary. It is found that, when the radius of the offset slot is about 0.38᎐0.62 times the radius of the circular patch, dual-frequency operat

## Abstract Designs of circularly polarized printed shorted annual and square ring‐slot antennas are proposed. Circular polarization (CP) radiation of the shorted ring‐slot antennas is achieved by selecting a proper length of the shorted section in the ring slot, which is about 3.9 and 8% of the me
