Abstract
A diversity antenna structure and a diversity transceiver incorporating the same. Each antenna of the diversity antenna structure is formed of a first portion and a second portion. Second portions of each antenna are coupled to an electrical ground plane and form thereby ground plane portions of the respective antennas. Such second antenna portions are maintained in physical isolation from one another thereby, when receiving high frequency signals, to be maintained in apparent electrical isolation from one another. Because such ground plane portions are maintained in the apparent electrical isolation from one another, antennas of the diversity antenna structure may be positioned in close proximity to one another without causing coupling between the separate antennas of the diversity antenna structure.
