Abstract

The present invention relates to an open-ended 1/4 wavelength resonance folded-slot antenna, the size of which is reduced to half of a planar antenna by means of magnetic wall effects, wherein the open-ended 1/4 wavelength resonance folded-slot antenna is formed by opening one end of a 1/2 wavelength resonance folded-slot antenna which has an input impedance that is effectively lower than a single slot antenna, so as to be easily utilized as a wideband antenna. For this purpose, the open-ended folded-slot antenna of the present invention comprises: a dielectric substrate; a ground layer formed beneath the dielectric substrate; a feed member which is formed on the dielectric substrate, and connected to the ground layer through a via contact to feed an RF signal; a connector connected to one end of the feed member to transmit/receive the RF signal to/from an external transmitter/receiver; and a radiating member which radiates the RF signal through a square C-shaped slot opened from one end of the ground layer. The thus-configured open-ended folded-slot of the present invention is small in size as compared to a folded slot antenna of the same frequency band, and achieves improved wave radiation efficiency at the side surface of the antenna.
