Abstract
A high efficiency antenna for the 824-960 MHz and/or 1710-2170 MHz frequency ranges including world cellular and ISM bands, for use primarily on wireless communications devices such as handsets. An antenna system may be integrated within a handset as a “pull-out” whip or as an internal antenna. The antenna uses an oriented PIFA-fed resonator working in conjunction with a ground plane conductor, which can be realized as the ground traces of the PCB printed circuit board and/or an extension of the ground plane of a wireless communication device. The antenna system when installed on a handset as a pull-out whip, requires approximately one-half the extended length of current pull-out antennas, thus improving the device's aesthetic and mechanical durability.
