Problems solved by technology

Since the size of the loop loop 16 is difficult to be adjusted after the proofing is completed, the bandwidth corresponding to the loop antenna 10 in the prior art is difficult to be corrected even if there is a drop

Embodiment Construction

[0035] figure 2 is a schematic diagram of a loop antenna according to an embodiment of the present invention. See figure 2 , the loop antenna 100 of this embodiment is suitable for a communication device. The communication device can be a mobile phone or a tablet computer, but the type of the communication device is not limited thereto. The loop antenna 100 includes a feeding end 110 , a grounding end 120 , a loop loop 130 , at least one first fine-tuning element 140 and at least one second fine-tuning element 150 .

[0036] The loop loop 130 is connected to the feeding end 110 and the grounding end 120 . The first fine-tuning element 140 extends from the circular loop 130 , and the first fine-tuning element 140 corresponds to a first frequency band. The second fine-tuning element 150 extends from the circular loop 130 , and the second fine-tuning element 150 corresponds to a second frequency band. The loop antenna 100 changes the bandwidth of the first frequency band o...

Abstract

The invention provides a loop type antenna which is applicable to a communication device. The loop type antenna comprises a feed-in terminal, a grounding terminal, an annular loop, at least one first tuning element and at least one second tuning element. The annular loop is connected to the feed-in terminal and the grounding terminal. The first tuning element extends from the annular loop and is corresponding to a first frequency band. The second tuning element extends from the annular loop and is corresponding to a second frequency band. According to the loop type antenna, the bandwidth of the first frequency band or the second frequency band is changed through adjusting the first tuning element or the second tuning element.

Description

technical field [0001] The invention relates to a loop antenna, in particular to a loop antenna with adjustable bandwidth. Background technique [0002] The research and development of communication equipment often follow the needs of the market, and launch models of different communication versions in stages. For example, Wireless Fidelity (Wi-Fi) is already common and indispensable in the minds of users, and the industry usually launches models with Wi-Fi versions first, and GSM (Global System for Mobile Communications) ( Global System for Mobile communication, GSM) or Long Term Evolution (LongTerm Evolution, LTE) models. Theoretically, when developing wireless fidelity models, designers will reserve space for antennas in lower frequency bands such as GSM or Long-Term Evolution technology, so as to save the time and cost of re-molding and redesigning the appearance . [0003] However, there are still some models that do not reserve space for low-frequency antennas. For ...
