Abstract
An object of the invention is to provide a slot array antenna in which unstable factors for contact of an adjustment portion comprising a slot waveguide and a waveguide holder are removed, a number of parts is decreased to save weight, and assembly is simplified. Accordingly, this invention is to constitute a radiation portion (1) unitedly formed of a slot waveguide (1a), a flare holder (1b), and a supporting portion (1d), if necessary, further adding a screen holder (1c) for a screen (4) for cross polarization suppression. Furthermore, this invention is to constitute a reinforcement feeder (2) unitedly formed of a feeder waveguide (2a), a reinforcement portion (2b) and a reinforcement connector (2c) in the case of an open type antenna.
Claims22
A slot array antenna comprising at least:
- a radome (5);
- a flare (3) arranged in said radome (5) and spreading continuously in a horn shape;
- a slot waveguide (1a) arranged at one end of said flare (3) and having a plurality of slots in an E surface thereof;
- a flare holder (1b) holding said one end of said flare (3);
- and
- a supporting portion for supporting said slot waveguide (1a);
- wherein a radiation portion (1) is constituted by forming said slot waveguide (1a), said flare holder (1b) and said supporting portion (1d) integrally.
