Problems solved by technology

[0007] Many manufacturers try to reduce the size of the antenna; however, the former (wire-wound ceramic rod) requires a large internal space, and the latter (PIFA antenna) is difficult to implement in mobile communication devices due to the distance between the antenna and the ground of the motherboard. The trend of light and small

Abstract

The invention provides a monopole system which is built in a mobile communication device. The monopole includes: a resonator that is coiled into a rectangle with open mouth shape, and has a first resonance path and a second resonance path, therein, the first resonance path is used for receiving signal with higher frequency width, the second resonance path is used for receiving signal with lower frequency width; a first rotary joint that is connected in an interface of the first resonance path and second resonance path, and is used as energy feeding device; and a second rotary joint that is fixed on an circuit board of the mobile communication device for connecting the first rotary joint. Therein, the first rotary joint feeds signal received by the first resonance path and the second resonance path into the second rotary joint, then transmits to front end of the mobile communication device RF circuit.

Description

technical field [0001] The invention relates to a monopole antenna system, in particular to a monopole antenna system built in a mobile communication device. Background technique [0002] The rapid development of the communication industry in recent years is due to the rapid advancement of the basic semiconductor industry and digital signal processing (DSP) technology, which drives the progress of the communication industry. As far as the three emerging fields of the communication industry are mobile communication, satellite communication and optical fiber communication, mobile communication is most closely related to individuals. With the rapid development of the communication industry, the demand for antennas used in the wireless communication industry is also becoming increasingly diverse. [0003] The wireless transmission function has become a necessary equipment for portable mobile communication devices. With the trend of products becoming thinner and smaller, how to ...
