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.

Radar Antenna Types

Following are the types of radar antenna:

Half-wave dipole
Quarter-wave dipole
Uniform linear array antenna
Non-uniform array antenna
Slot antenna
