摘要: A radio wave absorber provided with a radio wave absorbing film formed on a substrate, the radio wave absorber being capable of absorbing radio waves over a broad frequency band and exhibiting superior radio wave absorbing properties even with a radio wave absorbing film thinner than 1 mm. A film forming paste suitable for forming a radio wave absorbing film that is provided in the radio wave absorber. In a radio wave absorber provided with a radio wave absorbing film formed on a substrate, a particular epsilon-type iron oxide is employed in the radio wave absorbing film and relative permittivity of the radio wave absorbing film is set to 6.5 to 65.

摘要: A high-frequency antenna element that is easily downsized even when an electromagnetic wave absorber is used, and is capable of protecting a receiving antenna unit by covering the receiving antenna unit, and provides a high-frequency antenna module including the high-frequency antenna element. The high-frequency antenna element includes a substrate, a dielectric layer, a receiving antenna unit, and a coating layer, in which the dielectric layer is laminated on the substrate, the receiving antenna unit is mounted on the dielectric layer, the coating layer covers a surface of the dielectric layer in a portion in which the receiving antenna unit is not mounted while the coating layer is in contact with entire side surfaces of the receiving antenna unit, and the coating layer covers at least a part of an upper surface of the receiving antenna unit.
