Abstract

PURPOSE:To constitute the radome excellent in power transmission rate, by taking equivallent the dielectric substance plate as the desired dielectric substance plate, through making holes on the plates and controlling the dielectric constant. CONSTITUTION:When the glass window is taken as the radome, the thickness of the glass plate 4 is selected as the electric length pi. But, by only this, the strength and the band width are deficient. Then, the matching plates 8 and 9 are provided before and after the glass 4 and the Chevichef type impedance transformer is constituted. There is often needed for odd value for the dielectric constant of the matching plates 8 and 9. Then, the method obtaining desired dielectric constant by making holes on the dielectric substance plate is considered. When the diameter and the distance of holes are selected sufficiently smaller than the wave length used, the relation between the dielectric constant epsilonr and the desired equivallent dielectric constant epsilonre is approximately epsilonre=epsilon<1->Rr, where; R=(area of holes/total area.
