Compact diversity antenna with weak back near fields

摘要: A compact diversity antenna is presented consisting of two electrically isolated orthogonal loop conductors joined at a midpoint. This midpoint also attached to vertical conductor which produces third mode operation from the first modes. The horizontal and may be constructed have various relationships with ground plane shapes sizes. Some possible feed arrangements for each antennas as well matching tuning circuits. All three elements are found relatively weak near electric magnetic fields on side where small in extent. feature provides reduced radiation into head neck cellular phone user.
