  • Energy diversity antenna
    Patent number: 5760747
    Abstract: An energy diversity antenna (100) includes a first antenna (103) and second antenna (113) positioned on a substrate (101). The first antenna is preferably a loop used for receiving radio frequency signals with H-field energy while the second antenna is preferably a monopole used for receiving radio frequency signals with E-field energy. The energy diversity antenna (100) is applicable for use in portable communications devices capable of diversity reception. It is particularly useful in geographic locations where reflections and multipath interference is a problem.
