Technical Field

In order to achieve the requirements of all-round, multi-functional, high-detection and high-tech as much as possible, more detectors and antennas with different functions are naturally derived; however, with the increase of ship systems and equipment, the installation space of antennas is getting smaller and smaller, so it is very important to arrange antennas reasonably to avoid signal interference and electromagnetic interference between antennas; in addition to the conventional GMDSS radio station equipment equipped in accordance with SOLAS regulations, such as ship satellite ground stations, medium and high frequency radio stations, very high frequency radio stations, weather forecast and other safety information receiving stations, GPS antennas, etc., there are also redundant backup radio stations, ultra-high frequency radio stations, and air defense radios for helicopter communications. Radio stations, satellite communication equipment, satellite TV receiving systems, and positioning detection devices are gradually becoming essential facilities. The wireless mobile communication market is expanding rapidly, covering all kinds of multimedia services. In a wireless environment where the amount of data transmission continues to grow and the transmission speed continues to accelerate, antennas, as core components of radio communication and detection equipment, play a vital role.

Based on the above, in order to ensure the rationality of the antenna layout and minimize the interference of other equipment on the transceiver station, the antenna must fully consider the limitations of the deck space when installing, and a reasonable and compliant layout is required.
