发明名称 DIVERSITY ANTENNA STRUCTURE HAVING CLOSELY-POSITIONED ANTENNAS
摘要 A diversity antenna structure (500) and a diversity transceiver incorporating th e same are provided. Each antenna of the diversity antenna structure is formed of a first portion (516, 525) and a second portion ( 520, 527). Second portions (520, 527) of each antenna are coupled to an electrical ground plane and form thereby ground plane portions of the respective antennas. Such second antenna (520, 527) are maintained in physical isolation from one another thereby, when receivi ng high frequency signals, to be maintained in apparent electrical isolation from one another. Because such ground plane portions are m aintained 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.
