3D circular embedded antenna mounted on coaxial feeding for future wideband applications

Abstract

This paper presents the simulation analysis of three dimensional circular embedded patch antenna mounted on coaxial cable for wideband applications. The proposed antenna design is constructed from taking a basic square substrate with ground at lower side which is fed by a cylindrical strip coaxial cable feed line satisfying the 50 Ω requirement. Two vertically symmetrical cylinder of equal diameter with perpendicular to each other are mounted on feed line; which acts as a radiator. High Frequency Structure Simulator (HFSS) is used to analyze the critical parameters and simulation results on the reflection coefficient/return loss, VSWR (voltage standing wave ratio), H-plane, E-plane, gain and radiation pattern of the proposed antenna at various frequencies. The antenna has ability to achieve the frequency range of 3.3–30 GHz along with 160%, 9.09:1 fractional bandwidth and bandwidth ratio (BWR), respectively.
