What is Radar Antenna and its Types : Top Manufacturers

A radar antenna is a critical component that transmits and receives radio frequency signals used for target detection, tracking, navigation, and surveillance. Common radar antenna types include horn antennas, phased arrays, parabolic reflectors, slotted waveguide antennas, and microstrip arrays used in aerospace, defense, weather and automotive systems.

Typically any RF 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.
