Abstract
Planar antennas comprise capacitively coupled antenna patches. A first antenna patch configured to radiate in a first frequency band is coupled to a transmitter/receiver. The first antenna patch is situated to capacitively couple radiation in the first frequency band and a second frequency band to second and third antenna patches, respectively. The first and second antenna patches extend antenna bandwidth in the first frequency band, and the third antenna patch is bent so that the antenna patches can be situated in a predetermined substrate area.
