TUNABLE MULTIBAND WAN ANTENNA FOR GLOBAL APPLICATIONS

摘要

An electronic device includes an antenna for a transceiver to operate in a plurality of frequencies. The antenna includes a first portion that is coupled to an elongate element and is configured to enable the transceiver to operate in a first low-band frequency and a first high-band frequency. A second portion is also coupled to the elongate element. The second portion is configured to enable the transceiver to operate in a second high-band frequency. A third portion is coupled to the elongate element and is situated between the first and second portions. The third portion is configured to tune the first and the second high-band frequencies associated with the first and second portions. A tuning element is configured to tune the low-band frequency associated with the first portion such that the first and the second high-band frequencies are not significantly affected by tuning the tuning element.
