A Novel Low Loss E-Plane Substrate Integrated Waveguide Narrow Wall Slot Antenna

A novel low loss E-plane Substrate Integrated Waveguide narrow wall slot antenna is proposed in this paper. The antenna operating frequency is centered at 18GHz and is built by soldering four printed circuit boards together as well as two copper sheets, one on the bottom that is solid and one on the top with slots cut in it. A waveguide has both vertical and horizontal current, copper strips are used for the horizontal current and plated vias are used for the vertical current. A short is placed at the end using the same method to create a standing wave.
