Abstract
In this work, we present a leaky wave antenna with an enhanced angular scan rate (ASR) using high permittivity materials. The proto-type leaky wave antenna consists of a copper-made rectangular waveguide filled with lead zirconate titanate (PZT). The effective permittivity of the rectangular waveguide is tuned by varying the thickness of the PZT. The antenna showed an ASR of 265°/GHz between 2.4 GHz and 2.6 GHz as the effective permittivity is 337, and an ASR 636°/GHz between 2.12 GHz and 2.23 GHz as the effective permittivity is increased to 813.
