A compact simple circular disk printed monopole Antenna for multiple applications

Abstract

This work presents simple circular patch printed monopole Antenna presented for ultra-wideband (UWB) applications, the proposed antenna has a dimension of 23mm*34mm*1.5mm fabricated on FR4 dielectric substrate material with dielectric constant 4.3. The magnitude of S11 < - 10 dB of the structure, which explains the fractional bandwidth of 2.76-17.15 GHz. The gain and antenna efficiency of the structure are 5.4dBi and 88%, respectively. The simulated results with commercial microwave studio simulator CST and compared with the commercial HFSS simulator are in relatively good agreement. All these properties suggest that the proposed structure has applications in WiMAX, WLAN, C-band, X-band and Ku-band, as well as various other applications in wireless communications.
