Problems solved by technology

[0003] We know that most mobile phones with dual antenna system design built-in antennas are usually able to cover LTE / WWAN operation, but this only considers 4G frequency bands
On the other hand, in order to meet the needs of future 5G applications, a MIMO antenna for 5G smartphone applications was developed, which is able to cover the 3300-3600MHz frequency band, however, the bandwidth of this multi-mode is too narrow to cover the new generation 4800-5000 MHz frequency band for mobile communication

Embodiment 1

[0030] Example 1, such as figure 1 as shown, figure 1 The geometry of the hybrid antenna array applied to 4G / 5G smartphones is given. Under this condition, the system substrate is made of a 0.8 mm thick FR4 with a relative permittivity of 4.4 and a loss tangent of 0.02 and a size of 140mm x 65mm, which is a size suitable for the latest smartphone models. A metal floor is printed on the back surface of the phone case as a system ground. In order to meet the requirements of smartphones, the total thickness of the antenna is limited within 5mm, such as figure 1 As shown in (a), two 4G antennas are symmetrically placed on the short side of the system floor, while six 5G antennas are printed symmetrically along the two long sides of the system floor.

[0031] In the 4G antenna composition of the present invention, the designed 4G antenna is composed of a pair of reconfigurable antenna arrays, which can cover the LTE / WWAN frequency band. It is composed of two 4G antennas, figure...

Abstract

The invention discloses a hybrid antenna array of a smart phone, which is composed of a 4G 2-antenna array and a 5G 6-antenna array. The 4G antenna can cover two bands of 824-960 MHz and 1710-2690 MHz, and S11 is less than -6dB. The 5G antenna module can cover two bands of 3300-3600 MHz and 4800-5000 MHz, and S11 is less than -10dB, which can meet the requirements of 5G applications. The measurement results of an S parameter, a radiation efficiency, an antenna gain and a radiation pattern further indicate that the antenna fully meets the requirements of an MIMO system, and the hybrid antenna array has a better application prospect for the future 4G / 5G smart phone antenna.

Description

technical field [0001] The invention relates to a hybrid antenna array of a smart phone and belongs to the technical field of antennas. Background technique [0002] In recent years, as 4G communication systems have matured, many institutions have now shifted their focus to research on next-generation communications (5G). The wireless communication network environment has become a mixture of various heterogeneous networks, and the development and application of multi-mode mobile terminals have aroused interest in the field of wireless communication worldwide. Therefore, multi-band and multi-mode smartphone antennas are a must for terminal devices, especially those using MIMO systems. In November 2017, the Ministry of Industry and Information Technology of the People's Republic of China issued a domestic mobile phone 5G operating license, And defines the frequency band division of the new generation of mobile communication. These frequency bands are divided into 3300-3600 M...
