An Overview of Elliptical Low Pass Filter by using Defected Ground Structure Method
Abstract: Calculation and differentiation of the response of elliptical low pass filter (LPF) with and without using defected ground structure (DGS) was done. In the present work, return loss, bandwidth and gain have been evaluated. All the designs are printed on the FR4 lossy substrate of dielectric constant ( ) of 4.3, substrate thickness of 1.6 mm and loss tangent of 0.02. Moreover, the effect of controlling parameters namely slots and …

RF Energy Harvesting from Wi-Fi Router in 2.45 GHz ISM Band
Abstract: In this paper, an experimental RF energy harvesting system using rectifying antenna (rectenna) to harvest ambient energy from Wi-Fi at 2.45 GHz is presented. The proposed circuit is a combination of RMPA, followed by a third order stepped impedance low-pass filter, matching network and rectifier using Schottky diode for microwave (RF) to DC conversion. The performance of the rectenna is simulated by electromagnetic simulator computer simulation technology (CST) microwave studio. …

Rectenna Design with Defect Ground Structure at 2.16 GHz
Abstract: AbstractThis paper presents the rectenna design for Wireless Power Transmission. The design would receive and convert microwave of 2.16 GHz to DC. Proposed rectenna is a combination of microstrip patch antenna, followed by stepped impedance filter and then matching circuit and rectifier circuit. A low-pass filter (LPF) at the input port of the rectifying circuit is used to suppress the high order harmonics. The IE3D software is used for the …

A New Dual Side Cut Corner Circularly Polarized Rectenna 2.45 GHz with DGS
Abstract: This paper introduces a new dual side cut corner circular polarized (CP) high efficiency rectifying antenna (Rectenna) array. The Rectenna consists of a truncated square patch antenna and a rectifying circuit. The Rectenna use a micro-strip patch antenna as a frequency 2.45 GHz and gain of 31.29 dB. The Rectenna circuit has a low pass filter (LPF) the maximum RF to DC conversion efficiency of the Rectenna is 68%.
