Abstract
A radar antenna is disclosed. The disclosed antenna includes: a dielectric substrate; a feed line for feeding RF signals that is formed on an upper portion of the dielectric substrate and has a linear form; a multiple number of radiators that are perpendicularly joined to the feed line and have a bent structure comprising a horizontal portion and a vertical portion; a matching element for adjusting impedance matching that is joined to an end of the feed line; and a ground formed on a lower portion of the dielectric substrate, where a length of the horizontal portion and the vertical portion is set based on a polarization angle of an RF signal that is to be radiated. The disclosed antenna can be manufactured with a simple structure and a compact size.
