摘要: A multi-band radio communication device with an antenna system that includes an antenna element and a parasitic element located in proximity to the antenna element. A tuning circuit is coupled to the parasitic element. The tuning circuit is variable to adjust the parasitic load on the antenna element to provide variable operating frequencies and bandwidths for the communication device.
