Abstract

The present invention relates to a controllable antenna module and an electronic device having the same. The controllable antenna module comprises a dual-frequency dipole antenna, a right-side reflector set and a left-side reflector set, wherein the dual-frequency dipole antenna has the low-frequency and high-frequency dipole radiators of the same polarization directions, the low-frequency dipoleradiator has the low-frequency positive and negative pole parts, the high-frequency dipole radiator has the high-frequency positive and negative pole parts, and the resonance frequency of the low-frequency dipole radiator is less than the resonance frequency of the high-frequency dipole radiator; the right-side reflector set is arranged at the right side of the dual-frequency dipole antenna and has the first low-frequency and high-frequency reflectors and a first loop, and a first diode of the first low-frequency reflector and a second diode of the first high-frequency reflector are in homodromous parallel connection with a first capacitor by utilizing the first loop; the left-side reflector set is arranged at the left side of the dual-frequency dipole antenna and has the second low-frequency and high-frequency reflectors and a second loop, a third diode of the second low-frequency reflector and a fourth diode of the second high-frequency reflector are in homodromous parallel connection with a second capacitor by utilizing the second loop. According to the present invention, a switching reflection effect is ideal, and the industrial application value is high.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a controllable antenna module and an electronic device with the controllable antenna module. Background technique [0002] The radiation pattern of the antenna varies according to the basic working principle of the antenna. For example, a dipole antenna (dipole antenna) can produce an omnidirectional (omnidirectional) radiation pattern, and a patch antenna (patch antenna) can produce lateral (broadside) radiation. field type. Various radiation patterns have different applications. For example, an omnidirectional radiation pattern is suitable for terminal devices so that the terminal devices can receive wireless signals from all directions. As another example, base station antennas, such as wireless access point antennas, may need to be able to generate radiation patterns in specific directions, so as to perform wireless communication with terminal devices located in various spe...
