Abstract
An antenna assembly including a ground plane and a radiator supported above the ground plane is disclosed. The radiator may include a slot to configure the radiator to be resonant in at least two frequency ranges and a grounding point coupled to the ground plane. The radiator may be a dual-band planar inverted F antenna (PIFA) having an upper surface opposite the ground plane. First and second antenna modules may be coupled to the upper surface of the PIFA. The first and second antenna modules may be patch antennas, such as stacked patch antennas.
