ABSTRACT:
A dual-band monopole antenna includes a ground plane. A metal plate is located a first distance from the ground plane and includes first and second portions connecting to form a first angle therebetween. A slot is formed in the metal plate that isolates a center portion of the metal plate. The dual-band monopole antenna communicates first radio frequency (RF) signals in a first RF band and second RF signals in a second RF band. A feed tab contacts an outer surface of the metal plate and is located the first distance from the ground plane. The first RF signals and the second RF signals are vertical polarized signals. The dual-band monopole antenna produces a radiation pattern that is omnidirectional in the azimuth plane and vertically polarized in a horizontal plane. The first RF band and the second RF band are independently tuned.
