A vehicle body embedded antenna device is provided that can be embedded in a recess of a metal body of a vehicle. A vehicle body embedded antenna device is provided with a plate-shaped antenna element (10), a circuit board (20), and a fixed conduction section (30). The plate-shaped antenna element (10) is arranged inside the bathtub-shaped part (1) at a configurable maximum height in the bathtub-shaped part (1) so as to be substantially parallel to the surface of the metal main body. The circuit board (20) is disposed inside the bathtub-shaped part (1) so as not to overlap the plate-shaped antenna element (10) when viewed from above, and has a feed part (21) connected to the plate-shaped antenna element (10). The fixed conduction part (30) is conducted with both the circuit board (20) and the bathtub shape part (1), and is fixed to the bottom of the bathtub shape part (1) through a mounting hole (2) formed in the bottom of the bathtub shape part (1).
本发明提供了一种车体嵌入式天线装置,其能够嵌入车辆的金属主体的凹部中。车体嵌入式天线装置包括板状天线元件(10)、电路板(20)和固定导通部(30)。板状天线元件(10)以大致平行于金属主体表面的方式在浴缸形状部(1)中以能够配置的最高高度配置在浴缸形状部(1)的内部。电路板(20)以从上方观察时不与板状天线元件(10)重叠的方式配置在浴缸形状部(1)的内部并且具有与板状天线元件(10)连接的馈电部(21)。固定导通部(30)与电路板(20)和浴缸形状部(1)二者都导通,并且通过形成在浴缸形状部(1)的底部的安装孔(2)固定到浴缸形状部(1)的底部。
