Compact, low-cost antennas for multiband telematics
applications on vehicles are described. The multifrequency band
antennas are variations on the printed inverted-F antenna (PIFA)
principle. One type of PIFAis a compact variation of a conventional
antenna while the other is a novel planar version customized for
different mounting positions such as bumpers, window, and roof
mount. In both derivations the dimensions are small and have been
specifically designed for low-cost production.
