As shown in Figs. 1-7, the antenna 1 according to an embodiment of the present disclosure includes a middle housing 10, an excitation sheet 20, a dielectric filler 30 and a matching network 40.
The middle housing 10 is disposed between a screen of the mobile terminal and a battery thereof to strengthen the structural strength of the mobile terminal. The middle housing 10 includes a metal middle support board 11 and a metal frame 12 surrounding the metal middle support board 11. The metal frame 12 is integrally formed with the metal middle support board 11, and the metal middle support board 11 may be located at a center of the metal frame 12 in a width direction (i.e. arrow C as shown in Fig. 1) of the metal frame 12. The metal middle support board 11 has a transverse slot 13 extending along a transverse direction (i.e. arrow A as shown in Fig. 1) of the metal middle support board 11 and a longitudinal slot 14 extending along a longitudinal direction (i.e. arrow B as shown in Fig. 1) of the metal middle support board 11. The metal frame 12 has a frame slot 15 extending along the width direction of the metal frame 12.
The transverse slot 13 and the longitudinal slot 14 run through the metal middle support board 11 along a thickness direction of the metal middle support board 11 (i.e., the width direction of the metal frame 12) respectively, and the frame slot 15 runs through the metal frame 12 along a thickness direction of the metal frame 12, in which the thickness direction of the metal frame 12 specifically is a thickness direction of a part of the metal frame 12, and also may be the transverse direction or the longitudinal direction of the metal middle support board 11. The transverse slot 13 has two closed ends in an extending direction of the transverse slot 13 (i.e., the transverse direction of the metal middle support board 11) . That is, two ends of the transverse slot 13 in the transverse direction of the metal middle support board 11 are closed respectively. The frame slot 15 has two ends in an extending direction of the frame slot 15, and the two ends of the frame slot 15 extend to two edges of the metal frame 12 and are open thereat, respectively. A first end of the longitudinal slot 14 is communicated with the transverse slot 13 and a second end of the longitudinal slot 14 is communicated with the frame slot 15, and the transverse slot 13 and the
longitudinal slot 14 intersect with each other to form a T shape.
The excitation sheet 20 is disposed at a side of the metal middle support board 11. Specifically, the excitation sheet 20 is disposed on the side of the metal middle support board 11 and includes a feeding unit 21 and an expansion radiation unit 22 connected with the feeding unit 21. The feeding unit 21 covers the transverse slot 13 in a width direction of the transverse slot 13. In an embodiment, the width direction of the transverse slot 13 refers to an extending direction of a shorter edge of the transverse slot 13. The dielectric filler 30 is disposed between the excitation sheet 20 and the metal middle support board 11, and is filled in the transverse slot 13, the longitudinal slot 14 and the frame slot 15. The matching network 40 is disposed on the metal middle support board 11 and is connected with the feeding unit 21 and the metal middle support board 11 respectively.
In an embodiment, the transverse direction of the metal middle support board 11 is represented by arrow A as shown in Fig. 1, the longitudinal direction of the metal middle support board 11 is represented by arrow B as shown in Fig. 1, and the thickness direction of the metal middle support board 11 or the width direction of the metal frame 12 is represented by arrow C as shown in Fig. 1.
With the antenna for the mobile terminal according to embodiments of the present disclosure, by using the middle housing 10 as an antenna radiator, the antenna signal is prevented from being shielded, and the structural strength of the mobile terminal is enhanced along with the reduced thickness of the mobile terminal.
Furthermore, by providing the transverse slot 13 and the longitudinal slot 14 which intersect with each other to form the T shape in the metal middle support board 11, providing the frame slot 15 communicated with the longitudinal slot 14 in the metal frame 12, and providing the expansion radiation unit 22 in the excitation sheet 20, a relatively wide frequency band can be generated by means of a signal excitation in form of a coupling feed.
In an embodiment, based on the transverse slot 13, the longitudinal slot 14 and the frame slot 15, a radiation path is formed via the metal frame 12 and the metal middle support board 11. The radiation path and the excitation sheet 20 radiate communication together with the matching network 40, so as to cover a wireless wide area network (WWAN) and a long term evolution (LTE) band, thus meeting the domestic communication.
As shown in Fig. 3 and Fig. 7, the metal frame 12 is divided by the longitudinal slot 14 and the frame slot 15 to form a first radiation path L1 and a second radiation path L2. The excitation
sheet 20 excites the first radiation path L1 by the coupling feed to generate a low-frequency resonance so as to cover 791-960MHz. The first radiation path L1, the second radiation path L2 and the feeding unit 21 are coupled with one another, and an extra resonance is generated by the expansion radiation unit 22 to enhance the high frequency bandwidth, so that a high-frequency resonance is generated to cover 1710-2690MHz.
Furthermore, the antenna 1 for the mobile terminal can expand the bandwidth to meet 2G, 3G and 4G communication without an electronic switch, thus saving the cost, avoiding the loss of introducing the switch, and improving the performance of the antenna.
In addition, the dielectric filler 30 is filled in the transverse slot 13, the longitudinal slot 14 and the frame slot 15 by means of the integral forming technology, which can isolate the excitation sheet 20 from the metal middle support board 11, and also can beautify the appearance of the mobile terminal while preventing impurities from entering.
Therefore, the antenna 1 for the mobile terminal has a relatively wide bandwidth, which can meet the 2G, 3G and 4G communication. Moreover, the antenna 1 according to embodiments of the present disclosure has a simple structure, a low cost and a less loss, and also can reduce the thickness of the mobile terminal and improve the appearance of the mobile terminal.
