Title: Plane array antenna
Inventor: KAWABATA KAZUYA
IPC: H01Q21/00
Filed: 1990-11-30
Abstract: PURPOSE:To reduce a feeding loss of a feeder and to miniaturize and lighten the weight by forming plural slots or plural slot pairs to a ground conductor plate at prescribed intervals along the lengthwise direction of a dielectric line while being in crossing with the dielectric line. CONSTITUTION:Plural slot pairs 20 comprising a couple of rectangular slots 20a, 20b penetrating through a ground conductor plate 11 in the broadwise direction along the lengthwise direction of a dielectric line L1 are formed to the ground conductor plate 11 so that a circularly polarized electromagnetic wave radiates almost in the same phase from each slot pair 20 when a microwave propagates through the dielectric line L1 at a prescribed interval. Then a rectangular slot antenna is constructed respectively of each slot pair 20 on the dielectric line L1 used for the feeder and when a microwave is made incident in one terminal of the dielectric line L1, the microwave radiates from the other side of the ground dielectric plate 11 via each of the slots 20a, 20b and each slot pair 20. Thus, the loss of the feeder in the antenna is considerably reduced and the entire weight is made light.

Abstract: PROBLEM TO BE SOLVED: To make it possible to form very fine and high-density projections on a disk surface by applying mask particles for forming microprojecting parts on the surface of a protective film by etching and executing the etching of the surface of the protective film until these mask particles are removed. SOLUTION: A magnetic recording film 2 is formed on a nonmagnetic substrate 1 and the protective film 3 is formed thereon. The very fine mask particles 8 having the etching rate or selectivity equiv. to that of the protective film are dispersed by a dispersion, etc., and are applied on the protective film 3. These particles are then subjected to a dry etching treatment by using reactive gases. At this time, the height of the projecting parts 6 is arbitrarily settable by the etching rate of the mask particles 3 and the protective film 3, the diameter of the mask particles 8 and treatment conditions. Then, the selectively is imparted to the etching rate of the protective film 3 by changing the sizes and material quality of the mask particles 8, by which the mask particles 8 are removed and the projecting parts 6 of the arbitrary height are formed.  As a result, the simplification of the stage for forming the projecting parts 6 is made possible.
