Transmission Line Model Analysis of Rectangular Patch Antennas

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Comparison between Rectangular and Circular Patch Antennas Array

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,...

Transmission Line Model for Slot-coupled Microstrip Reflectarray Antennas

A transmission line model is adopted for the analysis of slot-coupled microstrip reflectarrays. The current on the equivalent impedance for the single radiating element is used to obtain the reflectarray phase design curve. Computational costs are drastically reduced with respect to theoretical full-wave analysis. Numerical and experimental validations are presented on the phase curve useful fo...

Analysis of a Rectangular Monopole Patch Antenna

A small printed monopole antenna for ultra wide band applications is proposed. The shape of the radiating patch considered is rectangular. The effect of the current distribution has been studied. The patch configuration is then modified to improve the impedance bandwidth. The dimensions of the patch and the distance between ground plane and radiating patch are optimized using the Genetic Algori...
