[need help] leaky-waves waveguide antenna

leaky waveguide antenna

Hello all!

I need more information on this topic - leaky waves in waveguides. long straight slots on waveguides narrow side.
in theory main beam in such an antenna has directivity:
cosθ=λ0\λw. where λw is waveguide wavelength.
I want to explore main beam and sidelobe parameters dependencies of slot parameters(length, width etc).
So if someone can advise any literature on this theme. i'll be very gratefull.

p.s. sorry for my english

Check following books for reference.
They are old books & you may get the information you want.

1) Radio engineering by Terman ( there are 2 books written by terman)

2) Waveguide handbook.

Hi, all.
I found some helpful information on this topic.

Dr.John_L.Volakis.Antenna Engineering Handbook Fourth Edition.pdf - there's a chapter in this book on this topic with lots of references to other works.

- a way to control sidelobes level in leaky-wave antennas. I simulated this structure in CST Microwave, but got zero result - sidelobes level the same as with straight long slot...
