THE CHARACTERISTICS OF SLOT ANTENNA, HORN ANTENNA AND APPLICABILITY IN MARINE RADAR

Abstract

Radar can be used as a general term for systems that used for detecting, locating and tracking objects or targets' position by different forms of energy. Radar technology is increasingly being expanded and applied in many different fields, such as using electromagnetic waves to explore underground, exploring and forecasting weather; use sound waves to probe in the human body, and probing underwater, measurement liquid level. Two types of antennas commonly used in detect radar systems are the Horn antenna and the Slot antenna, with different characteristics that be applied in respective different fields respectively. This paper will research and simulate the design of them, surveying the characteristics and comparing the graph of them on the S and X bands, thereby conclusions on the suitability of using two types of these antennas in practice.
