Abstract
The invention provides a radio communication device, which comprises a housing and a circuit board, wherein the circuit board is provided with a signal transmission end and a grounding end; the housing is made from a conductive material and is electrically connected with the signal transmission end and the grounding end; and the housing, the signal transmission end and the grounding end form a loop type antenna.
Description
Technical field
The present invention relates to a kind of radio communication device, relate in particular to a kind of miniaturization radio communication device.
Background technology
Along with developing rapidly and the raising day by day of people's living standard of wireless communication technology, mobile phone, personal digital assistant (personal digital assistant, PDA) etc. portable radio communication device competitively emerges in large numbers, and becomes the indispensable part of modern's daily life.In these radio communication devices, being used for the antenna structure of transmitting/receiving wireless signal is one of its most important assembly.
Along with the radio communication device overall development trend of miniaturization day by day, the miniaturization of antenna structure also becomes an important problem.For example, the working frequency range commonly used of multiple existing radio communication device is about 2.4GHz-2.5GHz, existingly is used to receive and dispatch the antenna structure that is in the wireless signal in this frequency range and generally need additionally provides a radiant body, to obtain to receive and dispatch preferably effect.Yet this existing antenna structure generally need take bigger installing space, is unfavorable for the miniaturization of radio communication device.
Summary of the invention
In view of this, being necessary to provide a kind of takes up space less and does not influence the radio communication device of transmitting-receiving performance.
A kind of radio communication device, comprise a housing and a circuit board, described circuit board is provided with a signal transmission ends and an earth terminal, described housing is made by electric conducting material and is electrically connected with the signal transmission ends of described circuit board and earth terminal, and described housing, signal transmission ends and earth terminal constitute a loop type antenna.
Compared to prior art, radio communication device of the present invention is set to a radiant body by described housing, and make itself and described signal transmission ends and earth terminal constitute a loop type antenna, with the blue bud operation frequency range that resonates out, do not need additionally to be provided with again an antenna radiator that is used to receive and dispatch blue bud signal, save the installing space effectively, helped the miniaturization of radio communication device.

Embodiment
See also Fig. 1, be depicted as the radio communication device 100 of preferred embodiment of the present invention.This radio communication device 100 can be mobile phone, personal digital assistant (personal digitalassistant, PDA) etc., it comprises that a housing 10, is installed in a circuit board 20 and two connectors 30 of housing 10, and this connector 30 electrically connects this housing 10 and circuit board 20.
This housing 10 can be the some of radio communication device shell, and its shape is tabular, is made by electric conducting material.This circuit board 20 be arranged in parallel with described housing 10, and it is provided with a signal transmission ends 22 and an earth terminal 24, provides the ground connection effect with the feed-in that is respectively applied for radiofrequency signal and for described radio communication device 100.
In the present embodiment, this two connector 30 is metal clips.Be appreciated that this two connector 30 can make for lead or by other electric conducting material.Wherein the two ends of a connection piece 30 electrically connect described signal transmission ends 22 and housing 10 respectively, make described housing 10 can obtain FD feed.The two ends of another connector 30 connect described housing 10 and earth terminal 24 respectively, make described housing 10 obtain ground connection.So, described housing 10 can double as one antenna radiator and is received and dispatched radiofrequency signal.
During 100 work of described radio communication device, signal enters described housing 10 from signal transmission ends 22, as mentioned above, this moment described housing 10 double as, one radiant body and constitute loop type antennas (figure is mark) with signal transmission ends 22 and earth terminal 24 are common.The size by adjusting this housing 10 and the frequency of FD feed can make this loop type antenna blue bud operation frequency range that resonates out, promptly make radio communication device 100 can receive and dispatch the wireless signal that is under the 2.4GHz-2.5GHz frequency range.
What Figure 2 shows that described radio communication device 100 returns loss (return loss, RL) measurement result schematic diagram.Generally (Voltage Standing WaveRatio is the frequency band that 2: 1 places use as antenna VSWR), and the return loss value equals-6 decibels (dB) herein with the voltage standing wave ratio of antenna.So the return loss value all can be used as the frequency band of antenna work smaller or equal to the-frequency range of 6dB.By described measurement result as can be known, when this radio communication device was worked under the 2.4GHz-2.5GHz frequency range, its return loss value all less than-6dB, all satisfied the requirement of wireless communication system.
Obviously, radio communication device 100 of the present invention is by being set to a radiant body with described housing 10, and make itself and described signal transmission ends 22 and earth terminal 24 constitute a loop type antenna, with the blue bud operation frequency range that resonates out, do not need additionally to be provided with again an antenna radiator that is used to receive and dispatch blue bud signal, save the installing space effectively, help the miniaturization of radio communication device.
In addition, those skilled in the art also can make various modifications, interpolation and the replacement on other form and the details in claim of the present invention scope of disclosure and spirit.Certainly, these all should be included in the present invention's scope required for protection according to the variations such as various modifications, interpolation and replacement that spirit of the present invention is made.
