Description

Tunable repeater antenna coupler and its manufacturing method {TUNABLE COUPLER FOR REPEATER ANTENNA AND MANUFACTURING METHOD THE SAME}

The present invention relates to an antenna coupler constituting a wireless repeater for mobile communication and a method for manufacturing the same, and more specifically, it can be installed and used in the middle of an antenna side transceiver end for a mobile communication repeater, and a tuning adjustment unit is provided for tuning. The present invention relates to a coupler for a tunable repeater antenna and a method of manufacturing the same, so that it is possible to easily perform and to remove an antenna interference signal through setting by tuning adjustment.

In general, a repeater for mobile communication is a device that receives a weakened signal in the middle of a communication system, amplifies and retransmits it, or shapes or distorts the waveform of a distorted signal, adjusts or reconfigures the timing, and transmits and receives the set radio frequency. It includes an antenna having a transmitting and receiving end.

Incidentally, the repeater amplifies the signal to reach the signal of the base station in the shaded areas that are difficult to reach, such as tunnels, underground parking lots, or radio wave blocking areas caused by mountains, buildings, or other topographic features. , It is a device that connects the signal of the shadow area terminal to reach the base station.

Such repeaters are widely used in that they reduce the cost required for operators to expand base stations in radio wave blind areas and ensure the performance to solve small shadow areas.

On the other hand, looking at the operation principle of the repeater, the base station signal received through the donor antenna is input to the low noise amplifier (LNA) through the duplexer to amplify low noise, and the amplified signal is mixed with the oscillation frequency of the local oscillator and down to the intermediate frequency. It converts, passes only the desired frequency band through a surface acoustic wave (SAW) filter with excellent skirt characteristics in the intermediate frequency band, and then upconverts it again, amplifies it in a high power amplifier, and sends it to a shaded area through a service antenna. do.

In addition, the signal of the terminal is received by the service antenna, amplified and filtered through the filter and amplifiers, and then connected to the base station through the donor antenna.

Such an antenna for a repeater generates leakage electromagnetic waves in which electromagnetic waves leak into a space other than the atmospheric space. In general, leakage electromagnetic waves are generated from a radiator and a coaxial cable portion of the antenna, and the generated leakage electromagnetic waves generate an oscillation signal that causes malfunction of the antenna. .

In addition, when receiving radio waves from the antenna for a repeater, there was a problem in that interference signals are introduced and confusion is disturbed, and thus, the call quality is deteriorated.
