Abstract

A mono-band planar inverted F antenna (PIFA) structure (200) comprises a planar radiating element (202) having a first area, and a ground plane (204) having a second area that is substantially parallel to the radiating element first area. An electrically conductive first line (210) is coupled to the radiating element (202) at a first contact located at an edge on a side of the radiating element (202). The first line (210) is also coupled to the ground plane (204). An electrically conductive second line (212) is coupled to the radiating element (202) at second and third contacts located along the same side as the first line (210), but at different locations on the edge than the first contact. Useable bandwidth of the PIFA is increased by using multiple contact locations to couple the conductive second line (212) to the radiating element (202). The first and second lines (210 and 212) are adapted to couple to a desired impedance, e.g., 50 ohms, at frequencies of operation of the PIFA.
