چکیده
In this article, a novel compact triple-band monopole antenna for WLAN/WiMAX applications is proposed. The proposed antenna is designed on an FR-4 substrate with thickness of 0.8mm, relative permittivity of 4.4 and loss tangent of 0.02. It consists of a square ring, an open ended stub, and an inverted T-shaped stub. Three bands covering 2.3–2.76, 3.387–3.73, and 4.97–6.28 GHz are achieved, which cover all the 2.5/3.5/5.5 GHz WiMAX and 2.4/5.2/5.8 GHz WLAN operation bands. Moreover, the presented antenna has a compact size of 24 × 36mm2. Experimental results show that the proposed antenna gives good gains and has nearly omnidirectional radiation patterns across all the operation bands.
