BROADBAND CAPACITIVELY-LOADED TUNABLE ANTENNA |
摘要 |
A broadband capacitively-loaded tunable antenna, and device there for is provided. The device comprises: an antenna feed; a first radiating arm connected to the antenna feed; a second radiating arm capacitively coupled to the first radiating arm; an adjustable reactance device connecting the second radiating arm to one or more of a ground and a third radiating arm; and, a processor in communication with the adjustable reactance device, the processor configured to adjust a reactance of the adjustable reactance device to tune a resonance frequency of a combination of the second radiating arm, the adjustable reactance device, and, when present, the third radiating arm. |
