A miniaturized quadruple‐band antenna with raster‐shaped patch is proposed. The proposed antenna can generate four separate impedance bandwidths to cover the 1.710–1.885, 1.850–1.990 GHz GSM operating bands, 2500–2690 GHz Extended UMTS operating band, 3650–3700 GHz and the 5.150–5825 GHz Wi‐Fi/Wireless Local Area Network (WLAN) band frequencies. The proposed coplanar waveguide‐fed antenna mainly consists of simple rectangular ground plane and developed raster‐shaped patch, which perform important role to produce all of four frequencies band. The designed antenna has a small overall size of 25 × 25 mm 2 and operates over the frequency ranges, 1.7–1.97 GHz, 2.45–2.8 GHz, 2.94–3.68 GHz, and 5.1–6.2 GHz suitable for GSM, Extended UMTS and Wi‐Fi/WLAN application. There is good agreement between the measured and simulated results. Experimental results show that the antenna gives monopole‐like radiation patterns and good antenna gains over the operating bands. © 2013 Wiley Periodicals, Inc.
