Embodiment Construction

[0026] In order to better illustrate the present invention, a further description will now be made in conjunction with the embodiments and the drawings.

[0027] The present invention is a multi-band parasitic antenna under harsh environment.

[0028] Such as figure 1 As shown, the present invention includes a plastic back cover 1 of a mobile phone.

[0029] Such as figure 2 As shown, the multi-band parasitic antenna in the harsh environment of the present invention further includes a monopole antenna 2 and a parasitic antenna 3 arranged on the back cover 1 of the plastic mobile phone.

[0030] The monopole antenna 2 includes a main feed point access part 2b, a first monopole part 2d and a second monopole part 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 monopole part 2d and the second monopole part 2c. Among them, the first monopole part 2d and the second monopole part The direction of 2c is on a...

Abstract

The invention discloses a multi-band parasitic antenna in harsh environments, and relates to the field of mobile phone antennas. The invention comprises a plastic mobile phone rear cover, a monopole antenna and a parasitic antenna arranged on the plastic mobile phone rear cover. The monopole antenna includes a main feed point access part, a first monopole part and a second monopole part in a "T" shape; the parasitic antenna includes a ground feed point access part, a first folding part , the parasitic body part, the second folded part and the end part; the first folded part, the parasitic body part, the second folded part and the end part are all located in the first monopole part, and the line where the second monopole part is located has no main feed point side of the access section. The invention effectively solves the problem that the internal environment of the mobile phone is complex due to the continuous compression of the space of the mobile phone, and further leads to the poor performance of the mobile phone antenna, effectively improves the communication performance of the mobile phone, and improves its use quality.

Description

Technical field [0001] The invention relates to the field of mobile phone antennas, in particular to a multi-band parasitic antenna under the harsh environment inside the mobile phone. Background technique [0002] With the continuous progress of mobile communication technology and the continuous improvement of people's aesthetics, communication equipment changes in various ways in order to adapt to the market. The miniaturization of equipment is a topic that constantly challenges its limits. As a result, the space of the antenna area of ​​the mobile device is continuously 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. [0003] At present, the existing antenna types are mainly PIFA, IFA, and monopole. These traditional antenna forms apply past experience to change the pattern and become more and more difficult. Among them, the inverted F antenna is li...
