Filed: 1987-05-15
Abstract: PURPOSE:To improve a gain and lope and to improve an input/output impedance characteristic in a primary radiator, by constituting a sub reflecting mirror so as to form a rotational parabolic plane, a cone plane, and a cylindrical plane to a main reflecting mirror continuously in recessed shapes, and constituting a wave from the primary radiator so as to be possible to be reflected in a parallel direction to the axis of the main reflecting mirror. CONSTITUTION:The sub reflecting mirror 2 is constituted in such a way that a point P is set as a focal point, and the rotational parabolic plane 2a is arranged on a center side, and the cone plane 2b rotating a straight line being inclined at 45 deg. for an axis Z around the axis Z, and the cylindrical plane 2c rotating the straight line in parallel with the axis Z are arranged continuously, and the mirror is formed in the recessed shape as a whole. Thereby, all of the waves radiated from the primary radiator 3 centering the focal point P, after being reflected on the rotational parabolic plane 2a geometric-optically, become the waves advancing in a direction of X-axis, and are made incident on the cone plane 2b, and are projected on the main reflecting mirror 1 as flat waves advancing in a direction parallel with the axis Z. In such a way, since no wave reflected from the sub reflecting mirror 2 on the primary radiator 3 geometric-optically exists, the impedance characteristic of the primary radiator 1 can be improved, and also, it is possible to form an aperture plane antenna with a few shielding areas for the main reflecting mirror 1.

IPC: G03F7/40
Filed: 1980-08-26
Abstract: PURPOSE:To etch SiO2 taperingly and continuously or discontinuously with high accuracy by port baking photoresist under different conditions. CONSTITUTION:A resist mask 3 is executed on the SiO2 2 on a Si substrate 1, and baked at 80 deg.C or lower and a slightly cured layer 3' is formed, and baked at 150 deg.C and an excellently cured layer 3'' is shaped on the surface. When the SiO2 2 is etched with HF, the SiO2 is etched in an isotropic shape because the film 2 and the layer 3'' closely adhere superiorly, but when etching reaches the layer 3' the SiO2 is etched taperingly because closely adhesive property between the layer 3' and the film 2 is inferior. Accordingly, the SiO2 can taperingly be etched variously by changing the conditions of the baking temperature and the accuracy of dimensions does not lower.
