Investigations on Broadband Microwave Discone Antennas

摘要

This paper presents Ansoft HFSS based parametric analysis and design of broadband discone antenna. The antenna is designed at 2.4 GHz which covers 2 ～ 20 GHz frequency band with return loss less than -10 dB. This bandwidth has been achieved by making a simple and easy modification in the design parameter of the antenna. The voltage standing wave ratio (VSWR) is less than 2 within the above specified frequency range. Radiation pattern of the antenna is bi-directional, with beam-width 80°. The proposed antenna has a wider bandwidth performance, compared to that of existing conventional broadband antennas.
