Analysis of Patch Antenna with Broadband Using Octagon Parasitic Patch

Abstract

This paper proposes a novel broadband octagonal patch antenna with parasitic patches. The proposed patch antenna is constructed with four parasitic patches around a central radiating octagonal element. It is illustrated that this arrangement can be used to improve the antenna bandwidth and gain when compared with that of conventional antennas. The proposed patch antenna is very simple, low-profile, and economical. The typical analysis of the proposed antenna is analyzed by the S11(S-parameter), the radiation pattern, and the realized gain. It can achieve an impedance bandwidth of 1.44 GHz and a high gain of 8.56 dBi in the 8.5 GHz band. Furthermore, the proposed antenna shows that the directional pattern and HPBW measurement results of E and H-plane were 70° and 74° at 8.5 GHz, and 74° and 83° at 9 GHz, and 47° and 42° at 9.5 GHz, respectively.

A Self-Adapting, Pixelized Planar Antenna Design for Infrared Frequencies

“…Radiation of the MSA can occur from the fringing fields between the edges of the patch and the ground plane. Although a microstrip patch antenna has a compact structure and low profile, MSA suffers from drawbacks like narrow bandwidth, typically 1–5%, and low gain and is unsuitable for wide bandwidth applications [ 37 , 39 ]. One of the attractive methods to obtain broad bandwidth is to cut part of the ground plane from the back of the radiator patch and, in this case, it can be considered as planar monopole antenna.…”

Design and simulation of a low return loss UWB CPW-fed patch antenna for mobile wireless communications

“…In [4], the design of compact CPW-FED dual band notched UWB square ring antenna with a bandwidth was depicted. In addition, an antenna bandwidth could be improved by using slots or adding parasitic patch around a central element [5][6][7]. The 3rd generation partnership project (3GPP) has allocated the spectrum for 5G in two ranges.…”
