An antenna cable connection module in accordance with the present disclosure includes an antenna cable for forming a contact point connected to an antenna filter part; a body part located on the outer circumferential surface of the antenna cable, and inserted into a receiving port located on the antenna filter part together with the end portion of the antenna cable and coupled to the antenna filter part; and a bush interposed between the antenna cable and the body part, and having an inclined surface having a slope in a longitudinal direction formed thereon to strengthen the coupling between the antenna filter part and the antenna cable. As a result, it is possible to constitute a simple antenna cable connection module of a ground contact type, thus providing a device reducing the failure occurrence rate. In addition, it is possible to constitute a simple antenna cable connection module for an operator to easily operate, thus reducing the labor cost and saving the time consumed for an antenna cable connection.

Antenna cable connecting module and method for producing antenna cable connecting module

The present invention relates to a dual-polarization antenna including an isolation providing device including: a transmission antenna element outputting a transmission signal provided via a feeder through a first port; a receiving antenna element receiving a reception signal so as to provide same to the second port; a first coupler distributing part of the transmission signal; an equalizer equalizing the distributed signal from the first coupler to a preset waveform; a second coupler receiving the output of the equalizer so as to couple same to a signal output to the second port; and a conductor forming a signal delivery path between the first coupler, the equalizer, and the second coupler. The coupling performance of the first and second couplers, the length of the conductor, and the functional characteristics of the equalizer are designed to allow a signal coupled to the second port through the signal delivery path using the conductor to have substantially identical amplitudes and a 180 phase difference, and an identical shape in an overall operating frequency band in contrast to a signal falsely inputted to a receiving antenna from the transmitting antenna element.
