Novel design of E-shaped patch antenna with dual-band EBG structure

In this paper, a novel dual-band modified E-shaped antenna is proposed for wireless application. In order to achieve the 2.4/5.8GHz dual-band performance, the stub structure is added into the E-shaped patch antenna. The effects of several fundamental design parameters of the novel antenna structure on reflection coefficient are investigated. It is found that the two operating bands of the proposed antenna can be obtained by choosing proper design parameters of the novel E-shaped patch. In addition, a dual-band electromagnetic-band gap (EBG) structure is applied to improve radiation performance.
