Abstract In present work a wide band and high gain cylindrical dielectric resonator antenna working in X-band has been designed and validated experimentally. First the bandwidth of the antenna has been enhanced by placing the thin dielectric layer between antenna and feed network. Next gain of the antenna has been increased by placing a layer of high dielectric material at nearly λ/2 distance as superstrate. The proposed design with impedance bandwidth of 3 GHz and gain nearly 11dBi could be used in satellite communication and other wideband wireless applications operating in X-band.

Abstract This work presents a wide-band active filter for RF receiver. The design uses Carbon Nanotube-FET (CNFET) based differential voltage current conveyor (DVCC) for the implementation of the proposed filter. The filter is designed to operate Ku-band frequencies (12-18 GHz), which is used in satellite communication. Additionally, CMOS based circuit and CNFET-based circuit for DVCC are compared for the performance evaluation. HSPICE simulations have been carried out to test the design aspects of the circuit. The CNFET-based circuit has better results in terms of 60 % reduction in the power consumption and about six times improvement in the bandwidth. The filter utilizes low supply voltage of 0.9 V and consumes 524 µW only. The proposed filter outperforms the existing CMOS-based designs which suggests its usage for low-power high-frequency analog circuits.
