An antenna system and a terminal device are disclosed. The antenna system may include a dielectric slab (); a clearance zone () on the dielectric slab (); a low-frequency antenna () with a working frequency band of less than 6 GHz arranged in the clearance zone (); a millimeter-wave array antenna () arranged in the clearance zone (); and a passive grid structure () arranged between the low-frequency antenna () and the millimeter-wave array antenna ().

Antenna system and terminal device

Provided in the present disclosure are an antenna, an antenna power supply method, a single-feeding-based method for combining antennas, and a terminal. The antenna comprises: a low-frequency antenna, a high-frequency antenna, and a filter. The filter is provided between the low-frequency antenna and the high-frequency antenna and isolates the low-frequency antenna and the high-frequency antenna. The low-frequency antenna and the high-frequency antenna use the same feeding point for feeding.

Antenna terminal with power supply and single feed combination

Provided is a multi-antenna terminal. The multi-antenna terminal includes a Printed Circuit Board (PCB), a first antenna, a second antenna, an inductance element, a first split-ring resonator group and a second split-ring resonator group. The first antenna and the second antenna are respectively connected to a grounding wire on the PCB; the first split-ring resonator group and the second split-ring resonator group are arranged between the first antenna and the second antenna; the first split-ring resonator group and the second split-ring resonator group are arranged in parallel, and respectively connected to a grounding wire on the PCB; one end of the inductance element is connected to the first split-ring resonator group, and the other end of the inductance element is connected to the second split-ring resonator group. The multi-antenna terminal can solve the problem that signals between respective antennas on the multi-antenna terminal interfere with one another in the related art, so that the use by people is more convenient. In addition, the multi-antenna terminal has the advantages of simple structure, lower cost and the like.

Multi-antenna terminal

A grounding structure is described in an embodiment of the present disclosure, which is applied to a rotary wireless access terminal, the wireless access terminal at least includes that: a structural part, as well as a main board and metal rotating shaft, which are arranged in the structural part, of the wireless access terminal, the metal rotating shaft is connected with an external interface of the wireless access terminal, wherein the grounding structure includes a metal dome and an insulating film; and one end of the metal dome is connected with the metal rotating shaft, while the other end is coupled to ground on the main board through the insulating film. A rotary wireless network card based on the above grounding structure is also described in an embodiment of the present disclosure. By the technical solutions of the embodiment of the present disclosure, an interference loop effect formed by a radio frequency current flowing through the main board may be effectively eliminated, the problem of poor low-frequency performance of a built-in antenna is effectively solved, and sensitivity of a low-frequency antenna is improved.
