0.42 THz Transmitter with Dielectric Resonator Array Antenna
(University of Waterloo, 2019-07-23)Off chip antennas do not occupy the expensive die area, as there is no limitation on their building material, and can be built in any size and shape to match the system requirements, which are all in contrast to on-chip ... -
Artificial Magnetic Materials for High Gain Planar Antennas
(University of Waterloo, 2011-03-30)A new method is proposed to enhance the gain and efficiency of planar printed antennas. The proposed method is based on using artificial magnetic materials as a superstrate for planar printed antennas while maintaining the ... -
Compact Electromagnetic Band-Gap Structures (EBG) and Its Applications in Antenna Systems
(University of Waterloo, 2013-02-22)This dissertation is focused on design of compact electromagnetic magnetic band-gap structures (EBG). Several popular compact techniques are introduced and analyzed with equivalent surface impedance model. A novel compact ... -
Disorder-based Electromagnetic Devices
(University of Waterloo, 2019-01-23)Engineered complex media with unusual and exotic electrical properties, realized through subwavelength building blocks, are leading to the development of new applications and improved functionalities in a variety of fields. ... -
Millimeter-Wave Band Pass Distributed Amplifier for Low-Cost Active Multi-Beam Antennas
(University of Waterloo, 2013-01-21)Recently, there have been a great interest in the millimeter-wave (mmW) and terahertz (THz) bands due to the unique features they provide for various applications. For example, the mmW is not significantly affected by the ... -
Phased-Array Antenna-in-Package Technology for Emerging Millimeter Wave Applications
(University of Waterloo, 2022-03-22)The ever-increasing data rates for wireless technologies (e.g., satellite communications, fifth generation (5G) wireless communications, and automotive radars) has directed the interests towards millimeter wave (mm-Wave) ... -
Theoretical and Experimental Study to Improve Antenna Performance Using a Resonant Choke Structure
(University of Waterloo, 2014-12-11)Every antenna requires a feed network to supply its RF energy. In the case of a simple dipole antenna, this could be a coaxial cable with a tuning element and matching balun. For mostly omnidirectional antennas, currents ... -
Theory, Design and Development of Artificial Magnetic Materials
(University of Waterloo, 2009-09-24)Artificial Magnetic Materials (AMMs) are a subgroup of metamaterials which are engineered to provide desirable magnetic properties not seen in natural materials. These artificial structures are designed to provide either ...
