The Fractional Bandwidth for thin slots can be as low as 3-5%; wide slots can have a FBW on the order of 75%. An example of a slotted waveguide array is shown in Figure 1 (dimensions given by length a and width b) Figure 1. Basic geometry of a slotted waveguide antenna.

Valizade, A., Ghobadi, CH., Nourinia, J., et al. A novel design of reconfigurable slot antenna with switchable band notch and multiresonance functions for UWB applications. Reflective array antenna - Wikipedia In telecommunications and radar, a reflective array antenna is a class of directive antennas in which multiple driven elements are mounted in front of a flat surface designed to reflect the radio waves in a desired direction. Radioengineering - June 2018, Volume 27, Number 2 [DOI: 10 The proposed antenna provides a wide impedance bandwidth of 10.35 GHz (3.05–13.4 GHz) covering the unlicensed UWB band. The simply structured antenna is easy to fabricate and to integrate in PCB board.
