Substrate Integrated Waveguide with Series Fed Antenna for Millimeter-wave 5G Applications

This paper describes the design of series feed antennas with two and four radiating elements. Both are designed to resonate at 26GHz. The proposed (1 x 2) and (1 x 4) series feed antennas are attached to a Substrate integrated waveguide (SIW). Over 0.75 mm tape around the antennas, the 0.5 mm vias diameter is attached by 0.9 mm space between visas. Gain increased from 10.6 dBi to 11.2dBi for the two elements' structure and from 13.5dBi to 14dBi for the four elements. The proposed structure encourages future work N x N elements to be developed by SIW and is used for 5G applications.
