HIGH GAIN TRAVELLING WAVE ANTENNA NOT REQUIRING IMPEDANCE MATCHING COMPONENTS

摘要

The present invention relates to a high gain traveling wave antenna not requiring a matching device, applicable to an array radiator and enabling a beam direction to be controlled by a simple signal input so as to improve a gain of an antenna in a limited space and effectively control the beam direction. The high gain traveling wave antenna includes: a microstrip line transmission line having a counterturn point formed on a substrate having a conductive ground plane on the rear surface thereof; a conductive via hole electrically connected to the conductive ground plane at one end of the microstrip line transmission line; and a radiator made of a conductor to be extended from the other end of the microstrip line transmission line.
