Design, Simulation and Analysis of Swastika Shape Uniplanar ACS Fed Antenna for Multiple Frequency Band Operation

摘要

A novel printed swastika shape ACS fed monopole antenna well suited to 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5 GHz WiMAX applications for tri-band operation is presented in this research. The proposed swastika shaped antenna encompasses of mirrored C shape strip, L shape strip, and meander shape strip with partial ground plane (alongside 50 Ω rectangular ACS feedline). Through the legitimate positioning of the appropriate length strips, desired multiple impedance bandwidths excited over 2.4/3.6/5.5 GHz centered frequency with a less than -10 dB standardized value of input impedance frequency response can be obtained. The prototype of swastika oriented configuration has been fabricated and experimentally validated its parameters with an admissible agreement perceived with simulated values. The simulated results of antenna covers frequency bands are 2.37 GHz to 2.57 GHz, 3.4 GHz to 3.94 GHz and from 5.0 GHz to 5.9 GHz for (S11< -10 dB). Also, the 2D radiation characteristics performance of designed structure at different frequencies are also observed and discussed.
