Abstract
An apparatus and a method for electromagnetic signal transition, comprising the steps of receiving an electromagnetic signal having a first physical characteristic arranged to be compatible for the electromagnetic signal to be transmitted on a transmission structure, and transmitting the electromagnetic signal to a substrate integrated waveguide, wherein during the transmission of the electromagnetic signal to the substrate integrated waveguide, the first physical characteristic is converted to a second physical characteristic arranged to be compatible for the electromagnetic signal to be transmitted on the substrate integrated waveguide.

A method for electromagnetic signal transition, comprising the steps of:
- receiving an electromagnetic signal having a first physical characteristic arranged to be compatible for the electromagnetic signal to be transmitted on a transmission structure;
- and
- transmitting the electromagnetic signal to a substrate integrated waveguide, wherein during the transmission of the electromagnetic signal to the substrate integrated waveguide, the first physical characteristic is converted to a second physical characteristic arranged to be compatible for the electromagnetic signal to be transmitted on the substrate integrated waveguide, wherein:
- the substrate integrated waveguide comprises a first metal sheet positioned at a first side of a substrate, and a second metal sheet positioned at a second side opposite to the first side of the substrate,
- the first metal sheet comprises at least one slot thereon,
- the at least one slot is elongated in shape and includes opposite sides, and
- wherein the electromagnetic signal at the opposite sides of each of the at least one slots are 180° out-of-phase.
