Abstract

In this article, a novel semicircular shaped mono pole antenna has been investigated for super wideband (SWB) applications with high bandwidth dimension ratio (BDR). The proposed antenna consists of semicircular shape patches and partial trapezoid ground plane. A tapered feed line is precisely connected to semicircle shaped patch, which provides extremely wide impedance bandwidth greater than ultra-wideband (UWB). The gap between the trapezoid ground plane and semicircular patch also plays a vital role to achieve wide impedance bandwidth. Studies of the antenna are performed using computer simulation tool HFSS. Prototype of the antenna is used for validation and verification for simulation results. Measurements to determine that the proposed printed antenna has an extremely wide impedance bandwidth (VSWR 2:1) from 1.30 to 20 GHz (175.58%) with a ratio bandwidth of 15.38:1 and BDR of 4261. 007 which is the highest among literature review. Furthermore, the proposed antenna also demonstrated a wide 14-dB bandwidth from 4.90 to 10.95 GHz, which is suitable for UWB outdoor propagation. The simple construction, much impedance bandwidth, average peak gain (4.18 dBi), and stable omnidirectional radiation pattern are a good deal sounder than the recently reported SWB antennas which make it appropriate for many wireless communication systems such as L band, WCDMA, ISM, Wi-Fi, LTE 2600, Bluetooth, WLAN, WiMAX, UWB, and MVDDS.
