摘要：

Background: In this paper, the design of a dual-band microstrip patch antenna with operating frequencies of 2.16 GHz and 2.79 GHz is proposed.Methods: The proposed antenna design is based upon the defected ground structure and rectangular patch with corner cuts. The presented antenna structure is simulated and optimized using CST microwave studio software.Results: The antenna resonates at 2.16 GHz and 2.79 GHz. The bandwidth of the proposed antenna is 2.08 GHz-2.25 GHz at center frequency 2.16 GHz and is 2.7 GHz-2.87 GHz at center frequency 2.79 GHz. The optimized antenna model is fabricated and measured. The measured and simulated results are presented and discussed. The proposed antenna provides a maximum gain of 4.463 dB and the maximum directivity of 5.846 dBi. The maximum radiation efficiency and total efficiency of the antenna are 79.85% and 69.01%, respectively.Conclusion: The proposed antenna is suitable for dual-band wireless applications. © 2020 Bentham Science Publishers.
