A LTE/WLAN antenna design for mobile handset applications

A novel multi-band broadband antenna for mobile handsets application is proposed in this article. An asymmetric T-type monopole antenna with a shorting-line is designed to be operated in long term evolution (LTE, 698MHz-960MHz, 1710MHz-2170MHz, 2500MHz-2690MHz) and wireless local area network (WLAN, IEEE 802.11ac, 5150MHz-5850MHz) bands. A prototype of the proposed antenna with 50 mm in length and 8 mm in width is fabricated and investigated experimentally. The experimental results indicate that the bandwidths for VSWR of 3:1 achieved were 37.75%, 24.63%, 11.46% and 21.76% at 800MHz, 1900MHz, 2600MHz and 5500MHz, respectively. The specific absorption rate (SAR) for an input power of 24dBm in LTE band, and an input power of 13dBm in IEEE 802.11ac band meet the SAR limit of 1.6 mW/g.
