Title: Antenna system
Inventor: UENO MOTOHARU
IPC: H01Q19/00
Filed: 1984-02-15
Abstract: PURPOSE:To easily cope with multiple beams with an antenna system and, at the same time, to improve the beam scanning characteristic of the device, by providing an auxiliary parabolic reflection mirror which commonly uses a focal point with a main parabolic reflection mirror and exciting the auxiliary parabolic reflection mirror by means of a Luneberg lens and feeding antenna. CONSTITUTION:A main parabolic reflection mirror 1 and auxiliary parabolic reflection mirror are provided with a focal point being commonly used by them and a Luneberg lens 7 and feeding antennae 81 and 82 which excite the reflection mirror 2 are installed. By means of the antenna 81 the lens 7 generates excited plane waves and the waves are again converted into plane waves by the reflection mirror 2 and radiated to the space from the effective area of the reflection mirror 1. Moreover, by arranging the antenna 82, beams corresponding to rays 52-62 can be obtained easily. When the radius of the lens 7 and wavelength are represented by R and lambda, respectively, the maximum distance (d) between the lens 7 and reflection mirror 2 is set to one which is equal to or smaller than the value shown by the formula and the maximum diameter of the lens 7 is set to one equal to or smaller than the maximum diameter of the reflection mirror 2. In this way, this antenna system can be used for multiple beams easily and its beam scanning characteristic can be improved.

Abstract: PURPOSE:To set an antenna elevation in a short time by fitting an inclinometer equipped with a pointer utilizing gravity and indicating the elevation of the effective area of a parabolic antenna in the direction of main beam to the parabolic antenna and adjusting the antenna elevation. CONSTITUTION:An antenna device is composed of an offset parabolic reflection mirror section 1, primary radiator 2, reflection mirror section fixing device 3, device 4 for adjusting the elevation of the device 3, device 5 for finely adjusting the elevation of the device 3, and inclinometer 6. The inclinometer 6 consists of a pointer 7, weight 8, mirror 9, and plastic box 10. The upper side surface of the box 10 is fixed to the back of the reflection mirror section 1 in parallel with the effective area D of the mirror section 1 and the pointer 7 is inclined by the weight 8 by the same angle as that of the effective area D. The mirror 9 is graduated in angle from 0 deg.-180 deg. and reading of the inclination can be taken accurately when the angle is read at the point where the pointer 7 lies on the image of the pointer 7 in the mirror 9. Therefore, the main beam direction of the parabolic antenna from its effective surface can be set to a prescribed elevation in a short time.
