A novel reconfigurable leaky-wave antenna is presented in this paper. The proposed structure is based on a half-mode substrate integrated waveguide. The antenna scans space electronically. This is accomplished by introducing novel metamaterial circular cells on the antenna. Sweeping the bias voltage causes the variation in surface impedance which results in beam-steering. The operating frequency is chosen as 28.5 GHz. The width, length, and height of the antenna are 45 mm, 69 mm, and 0.3 mm, respectively. Low profile, electronic beam-steering capability, and high gain of the proposed antenna make it a suitable candidate for 5G wireless networks.
