摘要：
A folded loop antenna having a very compact size of 5 x 8 x 60 mm(3) with multiband operation for ultra-thin smartphone applications is proposed. The antenna generates four resonant modes, the traditional 0.5-lambda, 1-lambda, and 1.5-lambda resonant modes and an extra higher-order 2-lambda resonant mode, to cover the GSM850, GSM900, DCS1800, PCS1900, UMTS, TD-SCDMA, LTE2300, and WLAN systems. The extra 2-lambda resonant mode is generated using a certain distance between the feed point and the shorting point on the ground plane. The antenna is studied using simulation and measurement. To study the antenna in a more realistic situation, a standard metallic USB connector is placed inside the loop radiator. Results show that the USB connector has little effects on the antenna performance.
