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.
Highlights
With high-speed technology and the rapid increase in demand, a microstrip patch antenna with compact structure, low profile, broad bandwidth, and easy integration is required [1]
We extended the bandwidth beyond 500 MHz through parasitic patches
The measurement of the impedance impedance bandwidth for the fabricated antenna yielded a broad bandwidth of approxibandwidth for the fabricated antenna yielded a broad bandwidth of approximately 1.44 mately
Summary
With high-speed technology and the rapid increase in demand, a microstrip patch antenna with compact structure, low profile, broad bandwidth, and easy integration is required [1]. A representative method for extending the bandwidth of the microstrip patch antenna is to chop part of the ground and increase the coupling induced between the antenna and the ground [4,5,6]. This method causes the loss of the directional radiation characteristic of these antennas, which is a unique characteristic. The proposed antenna minimizes structural changes in the ground, maintains the directional radiation characteristics, and has a fractional bandwidth of 10% or more [7,8]
