A Planar Monopole Antenna for L-Band Applications
Abstract: AbstractThis paper presents a square monopole antenna for L-band application, it is designed to be used in a 879 MHz–2113 MHz frequency bands. It is printed on dielectric substrate of FR4 glass epoxy with relative permittivity (ɛr) of 4.3, thickness of 1.6 mm, a square monopole antenna (aluminium sheet) is mounted on half ground plane via a single feeding strip. Prototypes of these configurations were manufactured and measured in frequency …

Analysis of Parabolically versus Exponentially Tapered Inbuilt Chip-to-Fiber Butt Coupler
Abstract: AbstractThe finite difference beam propagating method (BPM) is one of the most powerful technique to investigate linear and nonlinear lightwave propagation phenomena in axially varying waveguides such as curvilinear directional couplers, branching and combining waveguides, S-shaped bend waveguides, and different types of tapered waveguides. BPM is also quite important for the analysis of ultra short light pulse propagation in optical fibers. To date numerous algorithms for BPM have been proposed …

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 …

Amelioration of Parameters of Antenna using Metamaterial with Negative µ and ε for WLAN
Abstract: AbstractIn this paper, a Rectangular Microstrip Patch Antenna with “Multi Discoidal Rings” shaped metamaterial cover is designed and replicate at a height of 3.276mm from the ground plane. The antenna along with the proposed metamaterial cover is designed to resonate at 3.36 GHz frequency (in S-Band). Proposed metamaterial cover significantly reduces the return loss and increases the bandwidth and efficiency of the antenna in comparison to rectangular microstrip patch antenna …
