Short-circuited microstrip antennas for multiband wireless communications

The investigations on short-circuited microstrip patch antennas, which are able to generate multiple resonance frequencies in the wireless communication bands, are reported. In these antennas, by properly choosing the positions of shorted posts, good impedance matching can be obtained. The multifrequency nature of the shorted patch, theoretically obtained using IE3D software, is verified by measurement. © 2006 Wiley Periodicals, Inc.
