INVESTIGATION OF CHARACTERISTICS AND DETERMINATION THE NUMBER OF SLOTS FOR SLOT ANTENNA USED IN MARINE RADAR

Abstract

Antenna technology is an important part of today's electronics and communications, the development of wireless transmission has always been associated with the development of antennas. According to usage requirements, high-frequency bands are being researched and used for communication, transmission, and telemetry purposes. In particular, slot antennas are being used commonly on the S and X bands of microwave bands in marine radar. This article will design and simulate the slot antenna and analyze in-depth antenna gain characteristics, wave impedance for each frequency band used by the slot antenna to obtain a specific assessment of the relationship between the number of slots, size with antenna gain. Hence, this article proposed an optimal design suitable for each frequency band of slot array antennas used in marine radar.
