Patent ID: 8072388

Claim:
A dual-band diversity antenna comprising: a ground plane; a first antenna system coupled to the ground plane and including elements that are configured as a half-wave dipole for operation in a high band as a high band main antenna, the high band main antenna being configured for driving in a differential mode and including a reflector element operative to provide directionality and beam reinforcement, the first antenna system further including elements that are configured as a dipole for operation in a low band as a low band main antenna, the low band main antenna being configured for driving in a differential mode and including a quarter-wave structure to which the low band main antenna dipole is coupled; and a second antenna system coupled to the ground plane and including elements that are configured as a dipole for operation in a high band as a high band diversity antenna, the high band diversity antenna being configured for driving in a common mode, the second antenna system further including elements that are configured as a dipole for operation in a low band as a low band diversity antenna, the low band diversity antenna having the ground plane as a counterpoise.
