<p>Disclosed is a planar spiral antenna with improved performance. The planar spiral antenna according to the present invention is a planar spiral antenna wherein one end of an antenna pattern is connected to a first feeding unit and the other end is connected to a second feeding unit, and the antenna pattern is arranged in a spiral shape. The planar spiral antenna comprises: a first antenna pattern unit with a predetermined width, wherein adjacent antenna patterns are arranged and formed spacing apart from each other at predetermined intervals; a second antenna pattern unit with a predetermined width, wherein adjacent antenna patterns are arranged and formed spacing apart from each other at predetermined intervals, and the antenna patterns cross a space between the first and second feeding units. The width and space of the first antenna pattern unit are narrower than the width and space of the second antenna pattern unit.</p> |
