Problems solved by technology

In order to withstand the mechanical environment when launching a satellite equipped with an antenna, if the diameter of the antenna is about 1m, even if it is metal, it needs a thickness of about 2 to 3mm, so the mass becomes heavy, so it is not suitable as a mass limit Larger antennas for mounting on satellites are used

Embodiment Construction

[0035] Embodiments of the present invention will be described below with reference to the drawings.

[0036] Refer to attached figure 1 , An antenna according to one embodiment of the present invention includes a first panel 10 , a second panel 20 parallel to the first panel 10 , and a feeding unit 30 . The power supply unit 30 is, for example, a coaxial connector, and includes a tip portion 31 and a flange-shaped emission portion 32 . The central conductor protrudes from the tip portion 31 .

[0037] The first panel 10 has an outer first thin metal plate 11 and an inner first dielectric plate 12 , and the second panel 20 has an outer second metal thin plate 21 and an inner second dielectric plate 22 . Each of the first thin metal plate 11 and the second thin metal plate 21 is made of copper foil. Each of the first dielectric plate 12 and the second dielectric plate 22 is, for example, a composite material dielectric plate.

[0038] In addition, this antenna has a metal p...

Abstract

Disclosed is an antenna capable of obtaining electrical continuity between a flange-shaped short part of a power supply part and a metal thin plate (for example, copper foil) even in the harsh temperature environment of a space environment. This antenna is characterized in that, with the tip (31) of a power supply part (30) inserted from the outside of a face plate (20) into a power supply part hole (50) of a metal thin plate (copper foil) (21), a dielectric plate (22), and a metal plate (ring-shaped metal plate) (40), multiple screws (60) are inserted from the outside of the flange-shaped short part (32) of the power supply part (30) into multiple insertion holes (65) of the flange-shaped short part (32), the metal thin plate (copper foil) (21), and the dielectric plate (22) and are screwed into multiple screw holes (70) of the metal plate (ring-shaped metal plate) (40), thus obtaining electrical continuity between the flange-shaped short part (32) and the metal thin plate (copper foil) (21) by means of direct contact.

Description

technical field [0001] This invention relates to antennas, and more particularly to antennas for mounting on satellites. The invention also relates to a method of manufacturing the antenna. Background technique [0002] Generally, this type of antenna is configured by using two metal plates and supporting the two metal plates in parallel by metal rings on the outer peripheral portions of the two metal plates. In order to withstand the mechanical environment when launching a satellite equipped with an antenna, if the diameter of the antenna is about 1m, even if it is metal, it needs a thickness of about 2 to 3mm, so the mass becomes heavy, so it is not suitable as a mass limit Larger ones are used for antennas mounted on satellites. [0003] Japanese Patent Document No. 2001-345634 (Patent Document 1) discloses a method of affixing copper foil on a dielectric plate and a method of affixing a coaxial coupling to a dielectric plate by welding or the like in paragraph “0015”. ...
