Abstract: PROBLEM TO BE SOLVED: To provide an antenna device using a dielectric resonator, which improves the direction dependency of an effective gain, changes a frequency for communication without changing outer dimension and maintains a communicable frequency width, even if it is miniaturized. SOLUTION: A dielectric antenna 31 is attached to a metallic housing 15, and a feeder 22 for signal communication is attached to the antenna 31. Communication uses the characteristic resonance frequency of the antenna 31. Thus, the directional dependence of the effective gain of a dielectric resonator antenna is improved.

Also, the characteristic resonance frequency becomes high and a communicable frequency width is also widened at the same time by making the shape of the antenna 31 a rectangular parallelepiped and further making a notch. The characteristic resonance frequency can be changed by adjusting the size of the notch.

IPC: B60C11/11
Filed: 1987-05-11
Abstract: PURPOSE:To reduce the generation of pattern noise by a method wherein, in a radial tyre for an automobile having a plurality of pitch array rows, phase deviation is provided for a repetition pattern between pitch arrays, and a relation between the phase deviation and the length of a repetition pattern and a distance between the pitch arrays is specified. CONSTITUTION:In a tread pattern, blocks 3 are arranged circumferentially at a specified period by means of main grooves 1 and auxiliary grooves 2 to form pitch arrays 4a-4c. A distance between centers of the pitch arrays, for example, a distance LO between central lines 6a and 6b of the pitch arrays 4a and 4b, a phase difference A of the repetition pattern of the pitch array, and a length LO of a repetition pattern in each pitch array are set so as to satisfy a relation formula of 6LP.LO<A<12LP.LO. This constitution forces propagation of vibration generated when the blocks of the pitch array are earthed or separated from a road surface to interfere with vibration generated from the adjoining pitch array for offset. Thus, the generation of pattern noise can be reduced.

Accordingly, the area of the light emitting unit can be reduced. In this manner, moderating vibration in which speed characteristics can be suppressed, and preferable light output waveform can be obtained.
