Planar PIFA telematics antennas
R. Leelaratne · 2005
This paper describes printed planar versions of the PIFA antenna for multi-band telematics applications on vehicles. The antennas are variations on the planar inverted-F antenna (PIFA) principle and may be customized for different mounting positions such as bumpers, window and roof mount. The printed antennas are small, have a VSWR specification of 2 or better and are designed for low cost production. Each antenna was designed for tri-band mobile telephone band coverage from 890 MHz to 2100 MHz. On-vehicle tests are described for the antennas located on glass and integrated into the bumper on a vehicle.
