A wideband periodic leaky-wave antenna (LWA) is proposed in this paper. By using lossy dielectric material inside the wedge-like guide as medium for wave propagation, a leaky mode is excited and results in widening the bandwidth. For certain tangential losses, this leaky-wave antenna achieves 20.34% 3-dB gain bandwidth with maximum gain of 19.7 dBi. The antenna experiences low side lobe level (SLL) in general and low cross-polarization over the operating frequency, making the antenna suitable for millimeter-wave (mm-wave) applications.
