A MULTIBAND ANTENNA WITH MIMO IMPLEMENTATION FOR USB DONGLE SIZE WIRELESS DEVICES

摘要

A compact multiband antenna is proposed for future 4G Long-Term Evolution (LTE) wireless devices of USB dongle. The antenna covers LTE band-3 (1710-1880 MHz)/DCS1800 and LTE band-7 (2500- 2690 MHZ based on S_(11) = -6 dB matching criterion. Next the multiple-input-multiple-output configuration of this antenna is investigated. Prototype antennas were fabricated and experimentally verified. Both measured and simulated results are presented.
