Embodiment Construction
[0032] The invention provides an antenna frequency band adjustment device and a method thereof. By increasing the feed point of the antenna and switching the feed point according to the working frequency band to increase the antenna bandwidth, the existing parasitic antenna is used again to make the parasitic antenna the main antenna, and the antenna works in a wider frequency range through debugging, which can Design an antenna with wider bandwidth and better performance in the existing space. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] Please also see figure 2 with image 3 , The antenna frequency band adjustment device provided...

The invention discloses an antenna frequency band adjusting apparatus and method. The antenna frequency band adjusting apparatus comprises an antenna body, a parasitic antenna, a CPU arranged on a PCB, a radio frequency transceiving module and a selection control module, wherein the CPU controls the connecting state of the selection control module according to a current working frequency band, and connects the parasitic antenna or the antenna body with the radio frequency transceiving module through the selection control module so as to enable the parasitic antenna or the antenna body to transmit and receive signals; therefore, the length of the antenna can be changed automatically; consequently, the bandwidth of the antenna can be widened effectively without changing the antenna space and the antenna size; and in addition, the working frequency band of the antenna can be changed, and the radiation performance of the antenna can be improved.
Description
technical field [0001] The invention relates to the technical field of antenna design for electronic products, in particular to an antenna frequency band adjustment device and method thereof. Background technique [0002] With the development of communication technology, communication equipment such as mobile phones has become an indispensable equipment for people. The LTE (Long Term Evolution, commonly known as 4G) technology has become an essential technical requirement for new mobile phones. There are many LTE frequency bands. In order to add more functions to communication devices such as mobile phones and meet the trend of thinning, mobile phones are getting thinner and thinner. This will compress the antenna space and increase the requirements and difficulty of antenna design. [0003] The block diagram of conventional antenna design for communication equipment such as mobile phones is as follows: figure 1 As shown, the radio frequency transceiver module 50010 is con...
