LEAKY COAXIAL CABLE WITH THE FUNDAMENTAL RADIATED MODE BEAM

摘要

A single beam radiation type leaky coaxial cable is provided to radiate the electromagnetic wave of a specific frequency band in a single mode without signal distortion by calculating a correlation between a radiation angle and the specific frequency band. A single beam radiation type leaky coaxial cable includes an inner conductor(110), a dielectric substance(120), and an outer conductor(130). The dielectric substance(120) compactly encloses a center line of the inner conductor(110). The outer conductor(130) compactly encloses the dielectric substance(120). A plurality of radial slots exposing the dielectric substance(120) along the center line of the inner conductor(110) are formed in the outer conductor(120) at the same interval. A frequency band(X) and a radial angle of an electromagnetic wave satisfy a following equation Y=90ln(X)-624. The radial slot is a square groove to have a rectangle shape or a square shape. The electromagnetic wave is radiated in a single mode.
