Electrically coupled multi-band antenna with reactance loading

In this paper, we present hexa-bands internal antenna (LTE (band-13&band-17)/GSM850/GSM900/DCS/PCS/UMTS-1) for Smart phone applications. Proposed antenna achieved wide band performance by electrically coupled feeding and a reactance loading on radiator pattern. An antenna has a small volume of about 2.5 cc with low profile (the height is 4.5 mm) and wide-band performance (low-band bandwidth is about 51 % at 931 MHz and high-band bandwidth is about 39% at 2085 MHz).
