Abstract (en)

Disclosed is a ceramic dielectric material for an antenna, which is held between the conductor and ground-side electrodes of the antenna and has a water absorption of 1.0% or lower. This ceramic dielectric material is preferably alumina or a CaTiO3-MgTiO3 ceramic material. A microstrip antenna built up of this ceramic material can not only receive radio waves of a specific frequency, but can be improved in terms of reliability as well.
