Abstract
Background/Objectives: A new Double-Band monopole antenna is proposed in this paper. Four improved prototype of the proposed antenna is investigated. Method/Statistical Analysis: Final structure consists of a C-shaped slot on the patch and a spiral stub in ground plane to operate in two bands and enhance the bandwidth. Numerical simulation is performed for the antenna with Ansoft HFSS13.0, which is a kind of simulation software based on Finite Element Method and Rsoft Photonics CAD as photonic software. Findings: The influence of a photonic crystal substrate on the performance of a monopole antenna is simulated. Photonic crystal has been used as substrate to increase the bandwidth and gain. The antenna has two resonant frequencies in 5 GHz and 10.5 GHz with impedance bandwidth of 56% and 52.38% respectively. The gain of designed structure is about 3.4 dB. Applications/Improvements: The proposed antenna can operate in Wireless LAN in the U-NII-2/2e bands (channel 52 - 140, frequency range 5.260 - 5.725GHz) for first the band and X-band for second band.
