Example Embodiment

[0016] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and the embodiments.

[0017] Reference figure 1 , figure 2 , image 3 , Figure 4 As shown, the all-metal back shell and metal ring mobile phone antenna include 3 antennas, main antenna MAIN, diversity antenna AUX and GPS / WLAN antenna. The main antenna MAIN radiating sheet includes radiating sheets 6, 7, 8 and a metal ring 5. The main antenna feed point is set on the radiator 7. The radiator 7 is in contact with the metal ring 5. The metal ring 5 is divided into two parts, the left end 5a and the right end 5b. The left end 5a is used as a high frequency branch, and the right end 5b is used as a low frequency branch. Of course, depending on the change in the position of the feed point on the metal ring 5, 5a can also be used as a low-frequency stub of the antenna, and 5b can also be a high-frequency stub. The diversity antenna AUX and GPS / WLAN antenna radiating pla...

Abstract

The invention discloses an antenna structure applied to a mobile phone with metal rings and an all-metal rear housing. The antenna structure applied to the mobile phone with the metal rings and the all-metal rear housing comprises the all-metal rear housing, an antenna holder, an antenna pattern on the antenna holder, a connecting terminal of feeding points, the metal rings serving as an antenna loop and an antenna loop connector on the holder. The mobile phone with the metal rings and the all-metal rear housing comprises a total of three antennas, namely, a main antenna MAIN, an auxiliary antenna AUX and a GPS (Global Position System)/WLAN (Wireless Local Area Network) antenna. A radiation plate of the main antenna MAIN comprises radiation sheets and a metal ring. A feeding point of the main antenna is arranged on the radiation plate, and the radiation plate is in contact with the metal ring to divide the metal ring into a left end part and a right end part. A radiation plate of the auxiliary antenna AUX and the GPS/WLAN antenna comprises radiation sheets and a metal ring. The metal ring is divided into two parts by a grounding point. The antenna structure applied to the mobile phone with the metal rings and the all-metal rear housing is simple in structure, compact in layout and capable of greatly saving antenna space and achieving integrated design of the metal ring and the metal rear housing of the mobile phone to meet the special needs of appearance.

Description

technical field [0001] The invention relates to radio frequency and wireless communication, and specifically relates to an antenna structure applied to a mobile phone having both a metal ring and a full metal back shell. Background technique [0002] With the vigorous development of information technology, people's demand for electronic products is becoming more and more diversified. Mobile phones are playing an increasingly important role in people's daily work and life. Metal texture has always been a popular choice for various digital products. Fashion elements, the metal mobile phone is like a mobile phone wearing armor, which is very aesthetic, showing a tough and noble temperament, which is loved by many consumers. The very popular Apple iphone and HTC ONE mobile phones are all designed with metal rings or metal back shells. The antenna is an important part of mobile communication, and the quality of the antenna in the mobile phone directly affects the performance of ...
