Specific embodiment

Fig. 1 and Fig. 2 is referred to, the radio communication device 100 of a preferred embodiment of the present invention includes circuit board 10, housing20th, antenna 30 and connector 40.In the present embodiment, the connector 40 can also other can be with through hole cooperation for rivet etc.Fastener.

A circuit board 10 substantially rectangular slab, its surface has metal level.Two adjacent drift angles of the circuit board 10Compartment of terrain is provided with a rectangular area respectively at place（Figure is not marked）.Each rectangular area opens up an installation for being used to install housing 20 respectivelyHole 11, and a wherein rectangular area is formed with the antenna 30, another rectangular area is non-metallic layer.The circuit board 10 is provided withSupport that radio communication device 100 realizes the electronic component of existing various functions（It is not shown）.

The housing 20 includes main body 21 and end 22.The main body 21 is the shell of radio communication device 100, and it is covered in electricityOn road plate 10, its mode that can be connected by screw is fixed on circuit board 20.

The end 22 is made up of metal material, including the second sidewall 223 and two that a first side wall 221, two is oppositely arrangedConnection end 225.Two second sidewall 223 is respectively perpendicular and is arranged at the two ends of the first side wall 221, so that the end 22 of " U " type is formed,The end 22 can be enclosed located at the one end of circuit board 10, and the first side wall 221, two second sidewalls 223 are put down with the edge of circuit board 10Together.Two connection end 225 is a lamellar body, is arranged to the two horizontal interval on the first side wall 221, on each connection end 225A location hole 227 is opened up respectively, and is equipped with internal thread, be used to be fixedly arranged on end 22 on circuit board 20.Preferably implement at thisExample in, two connection end 225 respectively positioned at the first side wall 221 1/3rd positions at, two location holes 227 respectively with installationThe correspondence of hole 11, when end 22 is enclosed located at 10 one end of circuit board, two location holes 227 are aligned with mounting hole 11 respectively.

One first radiant section 31 that the antenna 30 includes being formed by the metal level in rectangular area, one second radiant section 33 andOne the 3rd radiant section 35, the rectangular area remainder is non-metallic layer.First radiant section 31, the second radiant section 33 and the 3rdRadiant section 35 is in strip, wherein, the length of the second radiant section 33 is slightly longer than the 3rd radiant section 35.Second radiant section 33 withTwo ends of 3rd radiant section 35 respectively with the first radiant section 31 are vertically connected.3rd radiant section 35 is away from the first radiant section 31One end is connected with a wherein mounting hole 11.

The connector 40 includes the stud 43 that a circular screw head 41 of screw head 41 and is extended downwardly.The outer peripheral face of stud 43 setsThere is screw thread, be used to wear and be locked in mounting hole 11 and location hole 227.

Also referring to Fig. 3, when stud 43 is arranged in the mounting hole 11 and its corresponding location hole 227 being connected with antenna 30When interior, circuit board 10 is fixed in end 22, meanwhile, the connector 40 as antenna 30 load point, and end 22 is then as dayThe partial radiation body of line 30, wherein, the 3rd radiant section 35, the first radiant section 31 and the second radiant section 33 are sequentially connected to form firstRadiation path, and the first working frequency range is obtained, first working frequency range is about；The connection end 225 being connected with load point and itsIn a second sidewall 223, and therebetween a part of the first side wall 221 formed the second radiation path, and obtain second work frequencySection, DCS and PCS, and with another second sidewall 223 and therebetween another part the first side wall 221 formed the 3rd radiation path,And obtain GSM and EGSM working frequency range.Also referring to Fig. 4 and table 1, be can be seen that according to test data, the radio communication device100 are respectively provided with preferably signal radiation effect under above-mentioned multiple resonant frequencies.

Each frequency band signals transmission/receiving efficiency of the radio communication device of table 1

Frequency range	GSM850	EGSM900	DCS1800	PCS1900	First working frequency range
						Transmitting efficiency	71.96%-80.88%	83.54%-83.92	78.97%-91.93%	80.78%-82.81%	80.44%-85.80%
Receiving efficiency	82.43%-84.16%	84.28%-84.76%	80.78%-82.88%	80.44%-85.80%	45.03%-67.24%

In addition, in order that circuit board 10 keeps relative stability with end 23, another connector 40 is arranged in another mounting hole11 and its corresponding location hole 227 in.

Metal end 23 is arranged at circuit board 10 by radio communication device of the present invention 100 by connector 40, andIt is connected with antenna 30 by connector 40, as some antennas radiant body, so that without in the main body 21 as metal shellOpen up antenna hole slot or the groove of antenna is installed, the complete appearance of radio communication device 100 can be protected, meanwhile, can also obtain manyIndividual many working frequency range, with preferably radiance.
