Abstract
The invention discloses a circular polarization waveguide crack panel antenna, which consists of three parts, upper radiation layer, middle layer and bottom layer. The upper radiation layer includes a resonator and radiation slot mainly to collect the energy from the middle and bottom layer and radiate into the air. The middle and bottom layer integrate to form the standard waveguide combination, achieving energy divider and feeding network polarized impedance matching.
Description
Technical field
At present Ku frequency range satellite television receiving antenna has the branch of linear polarization and circular polarization receptions, the circular polarization electromagnetic wave have rain decline little, receive polarization and change advantages such as little, therefore be the use of numerous satellite company.
Background technology
Use also just generation thereupon when the advantage of circularly polarised wave gets the nod, No. 2 direct broadcasting satellites of the prosperous promise of China use the circular polarization emission to promote the development rapidly of circular polarized antenna commercial market.
Summary of the invention
The present invention is a kind of Ku of being operated in frequency range circular waveguide leaky plate antenna, and antenna adopts upper, middle and lower-ranking to constitute, and middle lower floor constitutes square wave guide feed, power division network, impedance transformer network
The present invention realizes the circular waveguide leaky antenna of a kind of high-gain, super bandwidth, easy processing.
