Abstract
An antenna having wide-band characteristics and a radio signal detecting device using the antenna are provided. The antenna having wide-band characteristics includes: an insulating substrate; a first conductive layer formed on the top surface of the insulating substrate, the first conductive layer having a predetermined width from the front end of the insulating substrate to the rear end thereof; a second conductive layer formed on the bottom surface of the insulating substrate; and first and second conductive plates. The rear end of the first conductive plate is attached to the first conductive layer, the rear end of the second conductive plate is attached to the second conductive layer, and the front ends of the first and second conductive plates are parallel to and separated from each other. The wide-band antenna has a simple structure thereby reducing the overall size of a device. Furthermore, the antenna does not employ a dielectric at a received terminal thereof, thereby minimizing return loss at high frequencies and effecting wide-band operation.
