摘要：
In a high-frequency transceiver apparatus (100) wherein an antenna substrate (2) made of a dielectric material and having an antenna conductor pattern (7) formed thereon is bonded onto one surface of a base plate (1) to transmit and receive a high frequency wave signal, the flatness accuracy of the surface of the antenna substrate (2) is set at λ/20 or less when λ denotes effective wavelength.
