Embodiment Construction

[0025] In order to better illustrate the present invention, further description will now be made in conjunction with the embodiments and accompanying drawings.

[0026] The invention is a multi-band parasitic antenna in harsh environment.

[0027] Such as figure 1 As shown, the present invention includes a plastic mobile phone back cover 1 .

[0028] Such as figure 2 As shown, the multi-band parasitic antenna in the harsh environment of the present invention also includes a monopole antenna 2 and a parasitic antenna 3 arranged on the back cover 1 of the plastic mobile phone.

[0029] The monopole antenna 2 includes a main feed point access portion 2b, a first monopole portion 2b and a second monopole portion 2c. One end of the main feed point access part 2b is connected to a main feed point 2a, and the other end is connected to the first unipolar part 2b and the second unipolar part 2c, wherein the first unipolar part 2b and the second unipolar part The direction of 2c is...

Abstract

The invention discloses a multi-band passive antenna in a malicious environment, and relates to the field of mobile phone antennas. The multi-band passive antenna in the malicious environment comprises a plastic mobile phone back cover, a monopole antenna arranged on the plastic mobile phone back cover and a passive antenna. The monopole antenna comprises a main feed point access part, a first monopole part and a second monopole part, and is T-shaped; the passive antenna comprises a ground feed point access part, a first folding part, a passive main body part, a second folding part and an ending part; the first folding part, the passive main body part, the second folding part and the ending part are located at one side without the main feed point access part of a beeline where the first monopole part and the second monopole part locate. The multi-band passive antenna in the malicious environment effectively solves the problems of complex inner environment of the mobile phone and poor mobile phone antenna performance caused by continuous compression of the space of the mobile phone, effectively improves the communication performance of the mobile phone, and increases the use quality.

Description

technical field [0001] The invention relates to the field of mobile phone antennas, in particular to a multi-band parasitic antenna in the harsh environment inside the mobile phone. Background technique [0002] With the continuous advancement of mobile communication technology and the continuous improvement of people's aesthetics, communication equipment has changed in various ways in order to adapt to the market. The miniaturization of equipment is a topic that constantly challenges the limit. As a result, the space in the antenna area of ​​mobile devices is constantly being compressed, and the location of the motherboard is becoming more and more expensive. The dense placement of various components makes the environment of the antenna system worse and worse. [0003] The existing antenna types are mainly PIFA, IFA, and monopole. It is becoming more and more difficult for these traditional antenna forms to apply past experience to change the patten. Among them, the i...
