A broadband, high‐gain substrate‐integrated waveguide (SIW) slot antenna fabricated on a PCB is presented in this article. Measured return loss reaches 25 dB at 45 GHz with the bandwidth of 4.72 GHz. The simulated gain is 9.6 dBi at 46.2 GHz and the efficiency is 96%. The measured gain is 7.8 dBi at 46.2 GHz. Good agreement is achieved between measured and simulated antenna patterns and return losses. It is shown that the antenna behavior can be enhanced by oversizing the bottom ground and properly selecting dimensions of top metal. © 2015 Wiley Periodicals, Inc.
