Abstract
A transmission line transition includes a waveguide tube section having a waveguide tube, a waveguide tube section that is formed of at least a dielectric substrate and a line transition section formed of at least a dielectric substrate disposed adjacent the waveguide tube section to cover the hole, a transmission line for transmitting the electromagnetic wave, and an antenna pattern that is disposed in the hole to be electromagnetically coupled with the transmission line. Each of the dielectric substrates has a plurality. of via holes disposed to surround the hole at a distance δ=an integer n×wave length λg/2 from the peripheral wall of the hole.
