Design and Performance Studies of an Elliptical Slot Circular Polarization Antenna for C-Band Wireless Applications

Abstract

A novel and subtle design of a circularly polarized

microstrip line feed elliptical slot monopole antenna with an

intention to use in C-Band (4-8 GHz) is proposed in this

communication. Due to notable as well as remarkable

performances, this small and compact antenna with ample

applications in the arena of wireless communication upholds its

strong position among the previous work of similar types. For

designing and simulating the proposed antenna for exploration

of its feasibility to use in the C-band wireless applications

especially satellite-based communication system, CST MW

studio is used. Different categories of calculations and

performance studies have been performed while maintaining a

suitable environment of free space for wireless communication.

The antenna with overall dimension of 50 mm × 30 mm × 0.836

mm, where the substrate is used is Teflon and Copper is used as

radiating patch as well as ground plane, is placed for evaluating

its performance in respect of return loss, radiation and total

efficiency, VSWR, gain, directivity, direction of surface current,

axial ratio (AR) bandwidth, and reduction of cross polarization

(XP). An impressive return loss (-41.7 dB) at the resonance

frequency and suppression of XP of 33.50 dB have been

accomplished with other marvelous results.
