Abstract

PURPOSE: To reduce number of components and to improve the mechanical strength by making a pole such as a cylinder or a pyramid wit an optional height with a dielectric, metallizing one side face and one of two bottom faces with plating or vapor-deposition so as to constitute a cavity and forming a spiral conductor line to the remaining bottom face.
CONSTITUTION: A current fed from a feeder 2 flows to a conductor line 1 formed incorporatedly onto a dielectric 4 and a radio wave is radiated efficiently from a part in which the circumference of the line 1 corresponds to one wavelength. Moreover, a radio wave radiated downward among radio waves radiated from the conductor line 1 is reflected in a cavity 3 formed incorporatedly with the dielectric 4, synthesized with the radio wave radiated upward, then a high radiation gain is obtained. Thus, the conductor line 1 and the cavity 3 formed incorporatedly with the dielectric 4, although the similar electric function is provided to that of a conventional component, do not required any tightening component such as a screw 6 because of the incorporated structure. Furthermore, since no base 5 is required, the antenna withstands shock and vibrations and the joint between the conductor line 1 and the feeder 2 is strengthened.
