WIPO Patent Application WO/2017/086750
Kind Code:

Abstract:
The present invention relates to an antenna. An antenna according to the present embodiment comprises: a dielectric substrate; a main monopole antenna formed on the dielectric substrate; a plurality of parasitic monopole antennas formed on the dielectric substrate and arranged with the main monopole antenna interposed therebetween; a grounding surface formed on the lower surface of the dielectric substrate; a ring-shaped transmission line formed on the lower surface of the dielectric substrate; a first short-circuiting element formed on one side of the transmission line so as to short-circuit a first part of the transmission line; and a second short-circuiting element formed on the other side of the transmission line so as to short-circuit a second part of the transmission line. According to an embodiment of the present invention, it is possible to implement beam steering without using passive elements, such as an inductor and a capacitor, and high-rate data transmission can be implemented by forming an orthogonal beam. The presented structure maintains pure L and C even in a situation that has a theoretically unlimited transmission rate. That is, the same does not interfere with implementation of a high transmission rate. This is because the propagation mode of the circular transmission line, which has been applied, is a TEM mode, and, according to the transmission line theory, no blocking frequency exists. Consequently, the proposed circular transmission line maintains pure L and C even if the transmission rate increases.
