A novel frequency beam‐scanning substrate integrated waveguide cavity‐backed wide slot antenna with a wide‐scanning angle and bandwidth is investigated. The wide slot etched on the metal substrate is not only the radiating element but also part of the feeding network, which makes the whole structure very compact. The experiment indicates that the design principle is correct. The measured results show that the antenna achieves an enhanced operating bandwidth of about 27% with the gain from 10.12 to 16.25 dBi and the corresponding scanning angle is from 12° to 62 ° across the band. Good accordance is obtained between the simulated and the measured results.
