Frequency-tunable antenna

Abstract

A frequency-tunable antenna includes a radiating element, a feeding terminal, a first ground terminal and a second ground terminal. The radiating element includes a first segment, a turning segment and a second segment. The turning segment is interconnected between the first segment and the second segment. The feeding terminal is disposed at the first segment of the radiating element, and electrically connected with the radiating element and the circuit substrate. The first ground terminal disposed beside the feeding terminal. The second ground terminal is arranged between the first ground terminal and the turning segment of the radiating element. A radio frequency switch mounted on the circuit substrate is selectively connected with either the first ground terminal or the second ground terminal, so that the frequency-tunable antenna transmits and receives a wireless signal in first frequency band or a second frequency band.
