Design of a wideband beam scanning Rotman lens array

Tekbaş, Damla Duygu
The design, manufacturing techniques and measurements for wideband Rotman lens are presented. Different design approaches are explained in detail. A step-by-step procedure followed through the design process of a Rotman lens is given. The design equations are derived for both the parallel-plate/waveguide and microstrip/stripline Rotman lens versions. Effects of the design parameters on the lens shape and performance are investigated. A microstrip Rotman lens operating in 8 GHz – 16 GHz frequency band is designed and manufactured. To this end, related theoretical and simulation studies are carried out. The measurement results are compared with the results of the simulation studies.


Design and development of a complex shear modulus measurement setup for viscoelastic materials
Özgen, Gökhan Osman (2005-01-01)
Details of the design and development study of a complex shear modulus measurement setup for viscoelastic materials have been presented in this paper. The new setup is specifically designed for measuring the complex shear modulus of pressure sensitive adhesives. The setup consists of a rigid block that is connected to a rigid fixture through two identical shear specimens of the viscoelastic material to be tested. The rigid block and the shear specimens resemble a single degree of freedom system. Once the fr...
Design of a GaN Based Integrated Modular Motor Drive
Uğur, Mesut; Keysan, Ozan (2018-10-25)
In this study, design procedure of an Integrated Modular Motor Drive (IMMD) is presented focusing on high power density. The design is based on a permanent magnet synchronous motor (PMSM) and GaN FETs. Fractional slot concentrated windings are used on the stator. Slot/pole combination and winding configuration is selected based on having low cogging torque and high winding factor. An extended motor drive inverter topology is proposed where 2-level voltage source inverters are connected both in series and pa...
Analysis and design of active annular ring coupled circular patch antenna
Gebeşoğlu, Durmuş; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2017)
This thesis includes the design, production and measurement of the active, dual band annular ring coupled circular patch antenna. The dual band operation is achieved by using stacked patches. 3 dB hybrid is used to obtain circular polarization. Effects of antenna parameters on the input impedance and frequency ratio between the resonance frequencies are observed. Design has been achieved step by step. Firstly, dual band operation is investigated by using stacked patches. An annular ring antenna and a circul...
Design, fabrication, and measurement of efficient beam-shaping reflectors for 5G mm-wave applications
Karaova, Gökhan Çağlayan; Ergül, Özgür Salih; Department of Electrical and Electronics Engineering (2021-5)
In this study, an optimization procedure to design corrugated passive metallic reflectors for the fifth-generation millimeter wave (5G mm-wave) applications, as well as the fabrication and measurement of the designed reflectors, are presented. Such reflecting surfaces can be used as passive repeaters in both indoor and outdoor applications to change the field coverage by redirecting incident beams into desired directions with controllable power distributions. The design procedure includes a heuristic optimi...
Design of a Printed Yagi Array Antenna with Additional Director Element for Broadband Radar Applications
Atabay, B.; Dural, G. (2019-01-01)
In this paper, design, simulation, production and measurement of a coplanar broad-band microstrip antenna printed on an alumina ceramic substrate is presented. Antenna may be used as an element in a radar applications operating at X-band (8 GHz-12 GHz). The antenna driven system consists of one more directors because of the requirements of directivity. The reason of using high dielectric substrates the antenna can be printed on very small spaces. Antenna in Package structure's temperatures rising up rapidly...
