Abstract:
1. A microstrip antenna comprising: an insulating substrate; a plurality of antenna electrodes disposed upon one surface of said substrate, each having a feed point for application of a radio wave signal; a ground electrode disposed upon the other side of, or in the interior of, said substrate, for supplying ground level; and a connection member that connects at least one antenna electrode among said plurality of antenna electrodes to said ground electrode, at least at one spot thereof which is different from said feed point of said at least one electrode, the connection member being configured such that at least one antenna electrode among the plurality of antenna electrodes is unconnected to said ground electrode; wherein said connection member is disposed at a location within a plane region occupied by said at least one antenna electrode when said at least one antenna electrode is seen in plan view, such that a direction of an integrated radio wave beam which is emitted from said plurality of antenna electrodes is inclined from a direction normal to said substrate by connecting said at least one antenna electrode to said ground electrode at said location.
