COMPACT DUAL BAND CIRCULAR PIFA

摘要

The PIFA (120) for capableing of double ISM band operations the present invention relates to a kind of non-rectangular shape uses single loop. The PIFA of dual frequency operation arrives radiating element, the radiating element in quasi- subregion (8) by using slot (11). The performance of double frequency-band PIFA realizes planar waveguide (CPW) feeder line (13) and antenna structure by integrated or micro-strip or Co.
