In this paper, we introduce a novel electronically steerable antenna. The proposed design is a substrate integrated waveguide based quasi-uniform leaky-wave antenna. Introducing sets of switches over the slots and biasing them non-uniformly enables the scanning capability. Due to non-uniform distribution of the bias voltage of the switches, we achieve large variation in the radiation patterns. The center frequency is chosen as 28.5 GHz to accommodate 5G wireless networks. The width, length, and height of the antenna are 24 mm, 68 mm, and 0.3 mm, respectively. Scanning capability, compactness, and simplicity of the proposed structure makes it a suitable candidate for 5G wireless networks.
