HIGH POWER 12-ELEMENT TRIANGULAR-GRID RECTANGULAR RADIAL LINE HELICAL ARRAY ANTENNA

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...

Circularly Polarized Rounded-Off Triangular Microstrip Line Array Antenna

The Japan Aerospace Exploration Agency (JAXA) plans to launch a geostationary satellite called Engineering Test Satellite VIII (ETS-VIII) in FY 2006. In this paper, a microstrip line array antenna, which has a very simple structure, is introduced to radiate a circularly polarized wave aiming at ETS-VIII applications. This antenna consists of a triangular conducting line with its vertexes rounde...

Rectangular Microstrip Patch Antenna with Triangular Slot

This paper describes the design of Rectangular Microstrip Patch Antenna with Triangular Slot (RMPATS) at a frequency of f = 2. 4 GHz. The proposed antenna has been designed by introducing a triangular slot in the rectangular patch. The FR4-Epoxy with relative permittivity 4. 4 and height 1. 6 mm is used as substrate material. Antenna is fed by coaxial probe feed. The proposed antenna have accep...

A Reconfigurable Radial Line Slot Array Antenna for WiMAX Application

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...
