Abstract

Abstract:

A novel compact multiband mobile phone antenna for 4G communication is proposed. Using meandered monopoles and multiple branches, the antenna can resonate in multiple bands. The antenna is compact in size 32 mm×15 mm×0.8 mm. It consists of two meandered monopoles both having a length of about 1/4 wavelength. The C-shaped strip resonates at 2 GHz and the F-shaped strip at 900 MHz. The antenna is directly fed by a 50 Ω matching transmission line. The two strips co-radiate by combining and coupling to each other to achieve bandwidth of 810 971 MHz and 14 952 786 MHz, covering GSM 850/900/DCS/PCS/UMTS/ LTE 2300/2500 and meeting the requirements of mobile phone antenna for 4G communication. A prototype is fabricated and tested, showing general agreement between simulation and measurement results.
