To provide an antenna device capable of restricting unwanted radiation from an antenna connection part.SOLUTION: A first antenna and a second antenna are connected to an antenna connection part 62, the antenna connection part 62 is connected to an eighth side conversion part 60. The eighth side conversion part 60 converts a signal transferred among a waveguide, the first antenna, and the second antenna. A dielectric layer is provided on a side surface of the antenna connection part 62, and a plurality of via holes 48 are formed in the dielectric layer along the periphery of the antenna connection part 62.SELECTED DRAWING: Figure 7 【課題】アンテナ接続部からの不要放射を抑制できるようにしたアンテナ装置を提供する。【解決手段】第１アンテナおよび第２アンテナは、アンテナ接続部６２に接続されており、アンテナ接続部６２は、第８側変換部６０に接続されている。第８側変換部６０は、導波管と第１アンテナおよび第２アンテナとの間でやりとりされる信号を変換する。アンテナ接続部６２の一方の面には、誘電体層が設けられており、誘電体層には、アンテナ接続部６２の外周に沿って、複数のビア４８が形成されている。【選択図】図７
