Abstract

The utility model relates to a built-in GPRS antenna for use on PC card. A winding type antenna is arranged on one end of a circuit board; a printed antenna is printedly arranged between the winding type antenna and a GPRS module. The utility model primarily make the volume of the winding type antenna reduce according to the designing of the circuit board and a mechanical case, therefore, the winding type antenna can be completely contained in the mechanical case of the GPRS wireless network card. A printed antenna for 900 MHz frequency range is printedly arranged between the winding type antenna and the GPRS module in order to strengthen the emitted energy and characteristics of the frequency range and to prevent the winding type antenna from fading as a result of dwindling in size. Besides, the winding type antenna is easy to obtain without redesigning the forms of antenna and modules, therefore, the utility model can largely save the costs of the designing and the parts. Furthermore, the volume of the entire GPRS wireless network card can be reduced in order to achieve the goals of widely application to extensive fields and being convenient to assemble.

Description

Be used in the in-building type GPRS antenna on the PC card

Technical field

The utility model be a kind of with the Wound-rotor type antenna according to the design of circuit board and mechanism's shell reduced volume, the Wound-rotor type antenna can be held in mechanism's shell of GPRS wireless network card fully, again between this Wound-rotor type antenna and GPRS module, seal is established the printed antenna that a 900MHZ frequency range is used, make not reason volume-diminished and cause the decline of emitted energy and characteristic of Wound-rotor type antenna, and can save the design and the cost of part, and dwindle the antenna of whole GPRS wireless network card volume.

Background technology

See also shown in Figure 1, be used for the antenna structure on the GPRS wireless network card A at present, be the main media of signal transmission mostly with Wound-rotor type antenna A1, it is to utilize pad A4 in circuit board A2, Wound-rotor type antenna A1 is connected mutually with printed circuit A5, and transmits signals to GPRS module A 6 by printed circuit A5; And this Wound-rotor type antenna A1 can transmit the signal of three kinds of different frequency ranges of 900/1800/1900MHZ;

But the length of this Wound-rotor type antenna A1 is longer, and thickness thicker (with mobile phone big or small identical), can't hold fully in the housing A3 of GPRS wireless network card A, and be exposed to outside the housing A3, the volume of GPRS wireless network card A is strengthened, and using or carrying the inconvenience that causes the user;

Moreover, if when the designer desires to dwindle the volume of GPRS wireless network card A, then must redesign antenna form or entire module, except that waste design time and cost, also its design can't be applied in other field, and usually be that This is what people generally disapprove of;

Therefore, how to provide the antenna improved of a kind of escapable cost, reduced volume, be the place of the technical difficulties of the present utility model people institute desire solution.

Another purpose of the present utility model is that a kind of applied in any combination of utilizing Wound-rotor type antenna and printed antenna is being provided, and can dwindle the volume of whole GPRS wireless network card, and need not redesign antenna form and module, and can save the design and the cost of part in a large number, reach easy to assembly and application in-building type GPRS antenna widely;

Its mainly be with the Wound-rotor type antenna according to the design of circuit board and mechanism's shell reduced volume, the Wound-rotor type antenna can be held in mechanism's shell of GPRS wireless network card fully, again between this Wound-rotor type antenna and GPRS module, seal is established the printed antenna that a 900MHZ frequency range is used, in order to emitted energy and the characteristic that strengthens this frequency range, make not reason volume-diminished and cause decline of this Wound-rotor type antenna, and this Wound-rotor type antenna is obtained easily, and need not redesign antenna form and module, so that can save the cost of design and part in a large number, advance the volume that can dwindle whole GPRS wireless network card, extensively reach purpose easy to assembly so that can use the field of extension.

A kind of in-building type GPRS antenna that is used on the PC card, it is combined by a Wound-rotor type antenna and a printed antenna, and wherein, this Wound-rotor type antenna is an end that is arranged on the circuit board, and is connected mutually with printed circuit with pad;

This printed antenna is that seal is located between Wound-rotor type antenna and the GPRS module.

Described a kind of in-building type GPRS antenna that is used on the PC card, wherein, this Wound-rotor type antenna can transmit the signal of three kinds of different frequency ranges of 900/1800/1900MHZ, and can reduced volume can be installed in mechanism's shell of GPRS wireless network card the Wound-rotor type antenna according to the design of circuit board and mechanism's shell.

Described a kind of in-building type GPRS antenna that is used on the PC card, wherein, this printed antenna frequency range is 900MHZ, in order to strengthen the gain of this frequency range.
