EIGHT SHAPE MICROSTRIP PATCH ANTENNA WITH CRESCENT SLOT FOR WIDEBAND APPLICATIONS

A new wideband small size Crescent slot Eight Shape Antenna (CSESA) with crescent slot is presented. A loss less material honeycomb dielectric of dielectric constant 1.11 is sandwiched between radiating patch and ground. The main motivation for this paper is to enhance the bandwidth of the Impedance. The simulation results verify that the proposed antenna has a 63 percent bandwidth for Return less than-10 dB which is around 3.2 GHz while covering S-Band (2-4 GHz) and C-Band (4 - 8 GHz) of microwave frequency bands. Different design parametric variation in proposed design is also discussed. The basic advantage of these designs is simple structure with no active element, no shorting pins and no vertical walls between the patch and the ground. The typical impedance behavior and far field radiation pattern characteristics of proposed configuration are presented. The antenna is designed, optimized and simulated using Electromagnetic (EM) simulation software. This antenna is suitable for wideband wireless communication systems.
