ABSTRACT:
The microstrip antenna of the present invention has a basic structure of a ground conductor plate, dielectric substrate and radiation conductor plate laminated together. On the dielectric substrate, upon which the radiation conductor plate is formed, two radio wave reflectors are placed parallel to each other facing across the radiation conductor plate. The two surfaces of the two radio wave reflectors that are facing each other are either perpendicular to the dielectric substrate, or else the interval between the two surfaces enlarges as they depart from the dielectric substrate. Due to this structure, by increasing the variation in antenna directivity, the antenna can be made less susceptible to noise generated from noise sources in the antenna vicinity. Moreover, the antenna can be small-sized since the radio wave reflectors can be placed close to the radiation conductor plate.
