T-Shape Eccentric Slot Stacked Microstrip Antenna for UMTS | Original Article
T shape eccentric Microstrip antenna with circular polarization radiation for UMTS(universal mobile telecommunication system ). The antenna have a thick air substrate of 5mm and stacked microstrip radiating patch, Where the return loss is less than -10 db. The results show that the dual band antenna, is able to achieve VSWR less than 2 and the return loss above the -10db.
