Description

Antenna monitoring system and method of operation thereof {SYSTEM FOR MONITORING ANTENNA, AND METHOD FOR OPERATING THE SAME} The present invention relates to an antenna monitoring system for monitoring an antenna by detecting the output of an antenna, which is a passive device, and a method of operation thereof. An antenna refers to a wire installed in the air to radiate radio waves into space for wireless communication or to induce an electromotive force through radio waves, and there are various types of antennas depending on their shape, function, and other factors. In order to radiate communication signals within a building, base stations or repeaters that receive and amplify signals from base stations and radiate them can be used. In such cases, a method in which multiple antennas are distributed to a single base station or a base station to radiate (Distributed Antenna System) is common. Figure 1 is a configuration diagram showing a configuration in which multiple antennas are generally installed in a distributed manner within a building for a base station or repeater. As illustrated in FIG. 1, a base station or repeater is installed, and a signal output from the base station or repeater (10) can be transmitted to a plurality of antennas (30) through a combination of a main transmission line (c) and a distributor (20), and each antenna (30) transmits the signal transmitted from the repeater (10) into space and transmits the signal to a terminal to provide a service. Typically, the antenna (30) only has the function of simply outputting a signal into the air, so there is a problem in that the transmission output status from the antenna cannot be checked and it cannot be detected even if the antenna is broken or not connected. In the past, as illustrated in FIG. 2, the antenna (30) could be connected to a measuring device (40) capable of diagnosing and inspecting the antenna's failure by connecting terminals (30a, 30b), and then the state of the antenna (30) could be checked using the measuring device (40). However, determining whether the antenna (30) is faulty using the measuring device (40) in this way has the problem that the antenna (30) cannot be operated during the diagnosis time because the antenna (30) must be disconnected when diagnosing the failure of the antenna (30), and also takes a long time to diagnose the antenna (30) and cannot be checked immediately after the failure occurs. Therefore, there is an urgent need for technological development to resolve such problems. Figure 1 is a configuration diagram showing a configuration in which multiple antennas are generally installed in a distributed manner within a building for a base station or repeater. Figure 2 is a diagram showing the measurement of a failure in a conventional antenna.
