Wide-band 4G Mobile Device Planar Antenna Using Couple Feeding Technique

Surajo Muhammad, Abdulmalik Shehu Yaro, Ibrahim Bala Alhassan

Abstract


This paper deals with the design and fabrication of a wideband planar antenna capable of operating at both the wireless wide area network (WWAN) and long term evolution (LTE) with frequency bands LTE2.6GHz/2.3GHz/WLAN2.4GHz and WWAN (DCS1800/PCS1900/UMTS2100) respectively, using the couple feeding techniques. The proposed antenna has two sides with one side containing a rectangular radiator loaded with two rectangular strip shorted to ground plane through a narrow meandered strip line. While the other side contains a rectangular coupling strip that is fed with 50Ω microstrip feed-line. Result comparison between, the measured from the fabricated prototype and the simulation shows that the antenna has a nearly omnidirectional radiation pattern. The -6 dB operation bandwidth of the measured and simulated antenna are 1.81 GHz to 2.97 GHz and 1.46 GHz to 2.81 GHz respectively. This shows that the designed antenna can operate in the mobile device environment.
