EFFECT OF VARYING CURVATURE AND INTER ELEMENT SPACING ON DIELECTRIC COATED CONFORMAL MICROSTRIP ANTENNA ARRAY

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...

Radiation Conductance and Pattern of Array Antenna on a Non-Confocal Dielectric-Coated Elliptic Cylinder

The formulation for the radiation pattern and conductance of axial slots array antenna on a dielectriccoated elliptic cylinder is presented. The coating is assumed to be non-confocal. The analytical solution, given here, is based on the eigen function technique and the addition theorem of Mathieu functions. The excited apertures are assumed to generate a TM polarized wave. Accordingly, the obta...

Analysis of Metamaterial Based Microstrip Array Antenna

Design of Rectangular Microstrip Patch Antenna Array

In this paper the rectangular microstrip patch antenna arrays has been designed for S, C and X-band application by using the IE3D simulator. Roger RT/duroid material with dielectric constant 2.2 and height 1.588 has been used as a substrate material. Microstrip inset line feed has been used for feeding the rectangular patch antenna. Here 1x2 and 1x4 patch antenna array has been designed using s...

Dual Linearly Polarized Microstrip Array Antenna

Recently, Multiple Input Multiple Output (MIMO) has become popular research topic among researchers for development of a new wireless communications technology. The system capacity can be increase with deployment of MIMO technique in the communications system. Thus, the used of high frequency bandwidth can be avoid since this method required high cost implementation. High transmitted power also...
