摘要:
An antenna is disclosed which is particularly suitable for use with a cellular mobile phone. The antenna may be mounted on the rear window of a vehicle, and it includes a current fed one-quarter wavelength radiator adapted for mounting on one side of the window. An electrically conductive inner transfer member is mounted on the inside of the window in alignment with the radiator and a pair of spaced field-cancelling conductors are attached to the inside of the window and are spaced from the inner transfer member. The central conductor of an RF coaxial cable is coupled to the inner transfer member and the surrounding ground conductor of the coaxial cable is coupled to the field-cancelling conductors. In one embodiment, the one-quarter wavelength radiator comprises a pair of parallel, spaced radiator elements. RF energy is transferred through the vehicle window and the drilling of a hole for coupling the radiator to the coaxial cable is unnecessary.
