Abstract
A PIFA is formed using a grounding plane in a printed circuit board and a metal chassis or shield. Rather than using the printed circuit board as the separator, an air gap or other gap than the printed circuit board is formed. The transmitter and/or receiver for the antenna may be mounted to the printed circuit board. The feed pin routes signals for the PIFA from the transmitter and/or receiver to the metal chassis or shield while being isolated from the grounding plane that acts as the radiating surface of the PIFA. Standoffs supporting the printed circuit board may be used to short, and another standoff may be used as the feed pin.
