Abstract: Disclosed are ultra-small, planar antennas. The antennas include a circuit board having a first side and a second side and an off-center connector aperture and connector pad; a connector perpendicularly engaging the off-center connector aperture and connector pad of the circuit board; and a radiating element positioned adjacent the off-center connector aperture on a surface of circuit board having a perpendicular connection in plane to the off-center connector pad wherein the radiating element is not positioned below the connector. The ultra-compact, meander line, planar antenna, such as a planar inverted F antenna (PIFA), can be incorporated into wireless networking devices operating in the 2.4 GHz WiFi band. The combination of meander line and antenna elements yield improved performance operating in either free space or connected to a ground plane. Its compact design makes it ideal for WiFi, ZigBee, Bluetooth, and 802.11a/b/g/n/ac applications.

The resulting antenna provides wide band performance between 700 MHz and 2700 MHz with improved efficiency compared with conventional antennas.
