Abstract
This disclosure provides a horizontal radiation antenna including a grounded conductor plate on the back surface of a multilayer substrate, a radiation element to which a microstrip line is connected on a front surface of the multilayer substrate, and a passive element on an end portion side of the multilayer substrate compared with the radiation element. An intermediate grounded conductor plate is provided within the multilayer substrate between insulation layers and faces the microstrip line. The intermediate grounded conductor plate defines a notch portion whose end portion side is open. The intermediate grounded conductor surrounds the radiation element and the passive element in the notch portion. The intermediate grounded conductor is electrically connected to the grounded conductor plate.
