Abstract: A multilayer substrate includes a first dielectric layer and a conductor pattern disposed in at least an interior of the first dielectric layer. A second dielectric layer formed of a different material from a material of the first dielectric layer is disposed on the multilayer substrate. At least one radiation element is formed on the second dielectric layer. A feeding wire connects the radiation element and the conductor pattern. The feeding wire includes a conductor pin that is conductive and extends in a thickness direction of the second dielectric layer. The conductor pin electrically connects the radiation element and the conductor pattern. Provided is an antenna-integrated type communication module having such a structure that the accuracy of circuit simulation is easily enhanced and the degree of freedom in selection of dielectric materials is large.

Abstract: An antenna apparatus includes multiple antenna elements each performing at least one of transmission and reception of radio waves. The coverage areas of main lobes of radiation patterns of the multiple antenna elements are overlapped with each other and the shapes of side lobes thereof are varied among the multiple antenna elements. With this configuration, it is possible to discriminate and acquire the signal of the radio waves coming from the coverage areas of the main lobes of the antenna from the signal of the radio waves coming from the outside of the coverage areas.
