Abstract :
A compact low cost multiband antenna design is proposed for future 4G Long term evolution (LTE) wireless devices of USB size and Bluetooth headsets. The printed inverted F- antenna (PIFA) type antenna structure is on a 1.6mm thick FR4 substrate. The Antenna covers LTE band-3 (1710-1880MHz)/ DCS 1800 and LTE band-7 (2500-2690MHZ) based on S11 = -6dB matching criterion. Radiation efficiency above 65% in the lower band and 80% in the upper band is achieved. Next the Multiple-Input-Multiple-Output (MIMO) configuration of this antenna is investigated. The MIMO configuration shows an envelope correlation (ρ) value of 0.5 which meets the required industry standards. Radiation efficiency is always above 60% for the MIMO configuration. Measured and simulated data are presented in this paper.
