Meanwhile, the continuous progress of communication technology makes the requirement of communication frequency band more and more, such as covering the frequency band span from low frequency 704MHz to high frequency 2690MHz of 2G/3G/4G, especially LTE 4G frequency band. The requirement of consumers on small wireless equipment increases the difficulty of antenna design, and the compromise method is to divide the frequency band of the antenna according to different regions, which results in a large investment in cost and research and development of manpower and material resources.
In the prior art, a low-band tuned antenna with a switchable inductor is proposed for the contradiction between small-sized equipment and the requirement of multiple communication bands. The antenna is composed of an antenna resonance element arm and an antenna ground, the shorter antenna arm works in a high-frequency band, the longer antenna arm works in a low-frequency band, and the short-circuit branch is coupled between the shorter antenna resonance arm and the antenna ground. A series inductor and a switch are coupled between the longer antenna resonating arm and the antenna ground, and an antenna feed is located between the short circuit branch and the series inductor and the switch. Adjusting the switch to configure the antenna to operate at a different frequency, the antenna being configured to cover an upper portion of the lower communications band when the switch is closed; the antenna is configured to cover a lower portion of the lower communication band when the switch is open. The high band resonance is relatively unaffected by the switch position and the communication band for high frequencies can extend from about 1710MHz to 2200 MHz.
In the process of implementing the technical solution of the embodiment of the present application, the inventor of the present application finds that at least the following technical problems exist in the prior art:
