摘要

Here an improved folded patch antenna with low profile and high gain is proposed. By loading slow-wave metamaterials structure and metal pillars, the antenna operates from 0.6 GHz to 2.1 GHz (111% fractional bandwidth) with the VSWR2. The profile height is 48.5 mm and 0.095. at 0.6 GHz. The measured gain is 4 dBi at 0.6 GHz. The average gain is 7.43 dBi over the entire bandwidth. Hence, it is an excellent candidate for the emerging multiband indoor base station application such as 700 MHz, CDMA800, GSM900, DCS1800, PCS1900, UMTS, and IMT2000, etc.
