Abstract
An array antenna device for use in a 300 GHz band includes a first layer in which antenna elements are arranged in a grid shape and a second layer stacked on the first layer. The second layer includes mixers that are arranged in grid regions overlapping the antenna elements in plan view, that each include an LO signal terminal, an IF signal terminal, and an RF signal terminal, with the RF signal terminals being electrically connected to the antenna elements. The second layer also includes LO signal lines provided to respective columns of the mixers. Each LO signal line is commonly connected to the LO signal terminal of the mixers of the same column. The second layer further includes IF signal lines provided to respective rows of the mixers. Each IF signal line is commonly connected to the IF signal terminal of the mixer of the same row.
