A novel short waveguide terminal load (patent pending) with broad bandwidth is proposed and demonstrated. A simple design procedure is developed for the proposed terminal load. For verification purposes, a terminal load over the frequency range from 6.57 to 9.99 GHz was designed, manufactured and measured. The simulated results are compared with the measured data, and good agreement is reported. The measured return loss is greater than 20 dB over the full waveguide operating band (R84 standard waveguide), its total length is less than 35 mm, which is about a half of a commercial load with the same performance.
