Title:
ANTENNA, COMMUNICATION MODULE AND STREET LIGHT
Document Type and Number:
WIPO Patent Application WO/2019/142673
Kind Code:
A1
Abstract:
According to the present invention, an antenna is attached to a post. This antenna is provided with a first conductor, a second conductor, a third conductor, a fourth conductor and a power supply line. The second conductor faces the first conductor in a first direction. The third conductor is positioned between the first conductor and the second conductor, while being apart from the first conductor and the second conductor, and expands in the first direction. The fourth conductor is connected to the first conductor and the second conductor, and expands in the first direction. The power supply line is electromagnetically connected to the third conductor. This antenna is attached to the post so that the first direction is generally parallel to the direction in which the post extends.
