ANTENNA ARRANGEMENT

摘要

An apparatus such as for example an antenna sub-assembly includes a multiband antenna circuitry (100) and feed circuitry (120). The multiband antenna circuitry (100) includes a resonator (102); a first ground port (106) configured to couple the resonator (102) to a common voltage potential; and at least one reactive component (104) disposed between the resonator (102) and the first ground port (106). The feed circuitry (120) includes: a signal feed port (122) configured to couple to a radio; a second ground port (126) configured to couple the feed circuitry (120) to the common voltage potential; and a feeding element (124) disposed between the signal feed port (122) and the second ground port (126), the feeding element (124) configured to inductively couple the feed circuitry (120) to the antenna circuitry (100) between the resonator (102) and the first ground port (106). In some example embodiments there is a variable reactance to enable the resonator to be tunable. In those and/or other embodiments there is a second and even third resonator for multiband operation.
