COMPACT DUAL BAND CIRCULAR PIFA

摘要

The present invention relates to a non-rectangular shaped PIFA capable of dual ISM band operation using a single power feed. The dual frequency operation of the PIFA is accomplished by using a slot in the radiating element to quasi partition the radiating element. The dual band performance of the PIFA is realized through the integration of either the microstrip or the Co Planar Waveguide (CPW) feed line to the antenna structure.
