Abstract

PURPOSE:To enable to obtain the best directivity at the time, by suitably switching the power feeding point of antenna provided with a car body. CONSTITUTION:A frame 1a provided with a trunk rid 1 constitutes a trunk rid antenna, which is provided with two power feeding points A, B so that directivity fed from the points A and B can be obtained. An antenna switching device is provided at the end of feeding lines 9, 10, and and depending on the condition of electromagnetic waves, one feeding or both simultaneous feeding is made. The change- over of antenna is made suitably depending on the degree of multipath and the intensity of electric field.
