摘要： Generally, an antenna module includes a plurality of monopole antenna elements (e.g., 3 to 4 antenna elements) that can be coupled together by one or more switches to provide for a tunable, wideband antenna module. For example, the switches may change the overall length of the antenna such that the frequency range of the antenna is changed. The frequency response may also be controlled by a low voltage micro sized varicap, or a varactor diode, and instantiated as a tuned, resonant matching filter network residing with the antenna module. Additionally, switches may be used to “switch in” and “switch out” capacitive elements to adjust the bandwidth of the antenna. The resonant matching filter network may then be used for fine tuning the frequency of that bandwidth.
