Title: Directive antenna for detecting position
Inventor: KONO KIMINORI
IPC: H04W88/02
Filed: 2000-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a directive antenna for detecting a position of a mobile terminal, which uses the mobile terminal so as to detect the azimuth or the position of the terminal in a digital mobile wireless system forming pico cells. SOLUTION: An inner helical coil (11) acts like a delay line so as to effectively reduce the perimeter of a double helical antenna (12) to be one wavelength or below. For example, adjusting the diameter and the pitch of the inner helical coil (11) configures the delay line where the velocity of a high frequency signal propagated in an axial direction of the inner helical coil (11) is halved so as to reduce the perimeter required to bring the directivity of the double helical antenna (12) in the axial direction to about 1/2 wavelength and then the antenna can be mounted on a mobile terminal.
