Problems solved by technology

However, this will lead to a large volume of the antenna system, which is not conducive to the miniaturization of mobile terminals, especially in devices with small volume, such as mobile phones and other equipment, if the antenna volume is too large, the volume of electronic equipment will be very large. Big

Abstract

The invention discloses a directional dual-frequency antenna which is characterized by sequentially comprising a low-frequency radiating unit, a high-frequency radiating unit and a PCB from high to low. The low-frequency radiating unit and the high-frequency radiating unit are fixed over the PCB through fixing studs. The low-frequency radiating unit is provided with an opening, and the PCB is alsoprovided with a high-frequency feed line, a low-frequency feed line, a 1 / 4 wavelength isolation short-circuit line and a coupling feed slice. By stacking the low-frequency radiating unit and the high-frequency radiating unit, the size of the antenna is effectively reduced, dual-frequency coverage is achieved, the isolation short-circuit line is increased, and the isolation between high and low frequencies is improved.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a directional dual-frequency antenna. Background technique [0002] The communication system is a combination of wired and wireless. The transmission and reception of space wireless signals are realized by antennas. It can be seen that the antenna plays a vital role in the wireless communication system. MIMO (Multiple-Input Multiple-Output) technology refers to the use of multiple transmitting antennas and receiving antennas at the transmitting end and the receiving end respectively, so that signals are transmitted and received through multiple antennas at the transmitting and receiving ends, thereby improving communication quality. It can make full use of space resources and achieve multiple transmissions and multiple receipts through multiple antennas. Without increasing spectrum resources and antenna transmission power, it can double the system channel capacity, showing obviou...
