Microwave energy harvesting has the potential to power low powered electronic micro systems. Here we propose a fractal antenna topology that may be used for the conversion of microwave energy into usable DC power. The design of a broadband antenna that uses fractal approach is investigated. Simulation results demonstrate that improvements may be obtained in bandwidth and gain characteristics of planar antennas by using fractal approach.

Design of an active microstrip array using a microwave circuit simulator
Demir, S; Toker, Canan; Hizal, A (1997-02-26)
An active antenna array design and simulation of this design with a microwave circuit simulator are presented. This active antenna array is a TV receive only (TVRO) antenna operating at 10 GHz. It is a 8x4 array of rectangular microstrip patch antennas. Eight low noise pHEMTs are placed in the antenna. Passive antenna characteristics are usually obtained by analytical techniques or using special softwares for this purpose. The numerical representation as well as the nonreciprocal nature of the active device...
Investigation of temperature profile in high temperature PEM fuel cell
Çağlayan, Dilara Gülçin; Eroğlu, İnci; Devrim, Yılser; Department of Chemical Engineering (2016)
High temperature polymer electrolyte membrane fuel cells (HT-PEMFC) are promising alternative energy sources for the future. As an advantageous tool in the design of a system, modeling requires less time compared to the experiments as well as its low cost. This study includes both isothermal and non-isothermal three-dimensional mathematical models for a HT-PEMFC having an active area of 25 cm2. Governing equations are solved by using Comsol Multiphysics 5.0 “Batteries & Fuel Cells” module, which is a commer...
Comparison of multi-phase interleaved boost converters with various coupled inductor topologies
Gökmen, Raşit; Bostancı, Emine; Department of Electrical and Electronics Engineering (2022-2)
Multi-phase interleaved boost converters are widely used in high power applications thanks to their high efficiency, high power density, increased output power capability and low input current ripple features. However, increasing the phase number results in an increase in the overall volume of the converter. In order to reduce the volume of the converter, inductors in multi-phase interleaved boost converters can be coupled. For a two-phase interleaved boost converter, loosely-coupled inductor (LCI), close-c...
Design of series-fed printed slot antenna arrays excited by microstrip lines
İncebacak, Mustafa; Alatan, Lale; Department of Electrical and Electronics Engineering (2010)
Series-fed printed slot antenna arrays excited by microstrip lines are low profile, easy to manufacture, low cost structures that found use in applications that doesn’t require high power levels with having advantage of easy integration with microwave front-end circuitry. In this thesis, design and analysis of microstrip line fed slot antenna arrays are investigated. First an equivalent circuit model that ignores mutual coupling effects between slots is studied. A 6-element array is designed by using this e...
Investigation of various options for numerical modeling of fluidized bedsI for a solar thermal application
Bilyaz, Serhat; Tarı, İlker (null; 2015-05-29)
Circulating fluidized bed solid particle absorption solar thermal energy system is a promising approach to solar thermal with thermal energy storage. For accurately modeling such systems, the fluidized bed numerical model should be correctly representing the behavior of the actual bed. There are several suggested partial semi-empirical models in the literature considering distinct phenomena related to fluidization and void fraction distribution in a fluidized be...
