Analysis of dual-fed circularly-polarized circular patch antennas for educational purposes

Abstract:

Approximated expressions for the radiation characteristics of dual-fed circularly-polarized circular patch antennas are addressed in this article. By fitting the antenna radiation pattern with a cosine function, a simple closed-form expression for the antenna directivity is obtained. As an example, a linear phased array of five right-hand CP elements is presented. In order to validate the proposed approach, our results are compared with simulations performed using the commercial IE3D™ software. © 2011 IEEE.
