Super-Wideband Compact Offset Elliptical Ring Patch Antenna for 5G Applications

The plan and investigation of a compact offset elliptical ring microstrip patch antenna with a tapered feed line are discussed in this article for super wideband applications. The offered antenna exhibits 188.56% impedance bandwidth (2.31–40.0 GHz). The offered antenna is a low-profile printed antenna and gives a ratio bandwidth of 34.63:1 and a bandwidth dimension ratio of 1732 respectively. The radiation pattern plots of offered antenna exhibit that it accomplishes the durable omnidirectional behavior throughout the impedance bandwidth range. The maximum gain of the offered antenna is 5.81 dBi. The measured results (radiation pattern and S₁₁) are in close agreement with simulated results, which reflects the authenticity of the offered design. Also, the flat group delay and desired isolation make this antenna suitable for many useful applications that include wireless access systems, broadband disaster relief applications, radio local area networks and very-small-aperture terminal.
