| Summary: | A grounded CPW transparent ultra-wideband (UWB) antenna for Ultra High Frequency (UHF) and microwave frequency application is proposed in this paper. The proposed antenna covers a bandwidth starting from as low as 500MHz to the upper limit of the FCC UWB bandwidth of 10.6 GHz. This enables the antenna to be used for a very wide range of applications ranging from narrow band UHF devices to high data rate UWB transceivers. The antenna is fabricated using AgHT-8 for the CPW and radiator patch on a 1mm thick glass substrate with an Indium Tin Oxide (ITO) ground. The AgHT-8 has a sheet resistance of 8 Ω . m while the ITO, a sheet resistance of 4Ω . m. The overall size of the antenna is 64 × 67mm2. The antenna has a consistent flat 10 dB return loss across the entire bandwidth. The antenna is suitable for integrating onto window glass of homes and buildings as it does not affect the aesthetics of the building. The AgHT-8 layer of the antenna additionally provides sun-shielding from harmful sun-rays and keeps the building cool thus conserving energy required for air-conditioning in hot climates. As such the antenna provides an integrated wireless communication and energy conservation solution for modern day homes and buildings. |
