TUNABLE MULTIBAND ANTENNA

摘要

A tunable multiband antenna includes a first radiation conductor spaced apart from a grounding conductor, a second radiation conductor spaced apart from the grounding conductor and connected to the first radiation conductor, a first tuning unit electrically connected between a signal source and the first radiation conductor and operable to provide different impedances and a second tuning unit electrically connected between the grounding conductor and the second radiation conductor and operable to provide different impedances.

1. A tunable multiband antenna adapted to be connected to a signal source for receiving a radio frequency (RF) signal and a signal ground therefrom, the tunable multiband antenna comprising:
a grounding conductor including a grounding terminal adapted to be connected to the signal source for receiving the signal ground therefrom; a first radiation conductor spaced apart from said grounding conductor; a second radiation conductor spaced apart from said grounding conductor and coupled to said first radiation conductor; a first tuning unit adapted to be connected between the signal source and said first radiation conductor and receiving the radio frequency signal from the signal source, said first tuning unit being operable to provide a selected one of a plurality of different impedances; and a second tuning unit connected between said grounding conductor and said second radiation conductor, and operable to provide a selected one of a plurality of different impedances.
