Radar Antenna Basics and Types

This page covers radar antenna basics, radar antenna types, and radar antenna vendors, manufacturers, or suppliers. As we know, an antenna is basically a source of EM (electromagnetic) waves as well as a sensor of EM waves.

The antenna used for operating a radar is referred to as a radar antenna. It’s designed to handle radar operational frequencies. Remember, the antenna size and frequency are inversely proportional to each other.

An antenna converts RF (radio frequency) electrical current into electromagnetic waves and vice versa. The following antenna parameters are useful in order to select the radar antenna for appropriate applications:

• Antenna Impedance
• Frequency
• Gain
• Efficiency
• Bandwidth
• Directivity
• Effective Length
• Effective Area etc.
