Comparison between Rectangular and Circular Patch Antennas Array

Dual-Frequency Patch Antennas

Dual-hequency patch antennas may provide an alternative to large-bandwidth planar antennas, in applications in which large bandwidth is really needed for operating at two separate transmitreceive bands. When the two operating frequencies are far apart, a dual-frequency patch structure can be conceived to avoid the use of separate antennas. In this paper, a critical overview of possible solution...

Comparison Analysis of Rectangular and Circular Patch Microstrip Antennas with Dielectric Superstrates

In this paper compared the characteristics of coaxial probe fed rectangular and circular patch microstrip antenna with and without Superstrates. The antenna designed at frequency of 2.4GHz(ISM band) and formulated using transmission line and cavity model analysis. In this paper experimentallyinvestigated the effect of dielectric Superstrates onthe parameters such as bandwidth, beam-width, gain,...

Method of Moment Analysis of Finite Phased Array of Aperture Coupled Circular Microstrip Patch Antennas

A full wave spectral domain method of moment along with reciprocity theorem analysis of finite phased array of aperture coupled circular microstrip patch antennas is presented. Both the electric surface currents on the patches and the equivalent magnetic current on the apertures are considered. Results of reflection coefficient magnitude, active input impedance, active element gain, efficiency ...

Determination of Resonance Frequency of Dominant and Higher Order Modes in Thin and Thick Circular Microstrip Patch Antennas with Superstrate by MWM (RESEARCH NOTE)

An accurate model named as the Modified Wolff Model (MWM) is presented as an efficient CAD tool for determination of resonant frequency of the dominant and higher order modes under the multi-layer condition in thin and thick circular microstrip patch antennas. The effects of dielectric cover on the resonant frequency obtained from MWM have been compared against the result of theoretical method ...
