A novel dual-broadband dielectric resonator antenna (DRA) is presented. Based on the modified Sierpinski gasket constructed though two iterations, the proposed antenna display both dual band and wideband features. The measured impedance bandwidths for S11 < −10dB are 2.25–2.60GHz (14.46%) and 3.10–4.10GHz (27.78%) respectively, which can cover the wireless local area network (WLAN, 2.4–2.484GHz)...
A simple multiband metamaterial-loaded monopole antenna suitable for wireless local area network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) applications is proposed in this letter. The rectangle monopole of the proposed antenna is originally designed to resonate at around 5.2 GHz. When the inverted-L slot is etched, the antenna produces a second resonance at around 4.1 GHz...
