UWB Circular Metal Mesh Transparent Antenna

This paper presents the design of a novel co-planar waveguide (CPW)-fed circular metal mesh (MM) transparent antenna (TA) for ultra-wideband (UWB) applications. To achieve transparency, the MM technique is utilized on both the conductor and the dielectric substrate. To achieve broadband impedance matching in the band of interest, the corners of the CPW ground are truncated in a curved pattern. It is observed from the simulation results that the proposed UWB MM TA is resonating from 2.88 to 20 GHz, offering an impedance bandwidth of 17.12 GHz. In addition, acceptable radiation characteristics are observed in the proposed design, which makes it suitable for indoor wireless infrastructure.
