Characterization of asymmetric annular-slot antennas and design of a tunable asymmetric annular-slot antenna with ferroelectric material
(2006)
A statistical characterization of an annular slot ring antenna using DOE is presented. The models give an understanding on the effects of the antenna design parameters on the responses of the antenna. These models are ...
Design and simulations of an integrated 9.41 ghz 24 channels phased array synchronization by phase locked loop for dual polarized doppler solid state radar for casa student test bed
(2012)
The design and simulations of an integrated 9.41 GHz- 24 channel passed array synchronization by phase looked loop for dual polarized Doppler solid-state radar for the CASA student Test Bed is presented in this thesis. The ...
Tunable folded-slot antenna with thin film ferroelectric material Ferroelectric material
(2003)
In this work, the modeled performance of gold (Au)/ Ba0.60Sr0.40TiO3 (BSTO) ferroelectric/ magnesium oxide (MgO) two-layered tunable coplanar waveguide (CPW) fed folded–slot antenna (FSA) is presented. BSTO materials have ...
Design of transceiver module for dual polarized doppler solid state radar for casa student test bed
(2009)
The design of a Transmit Receive Solid State Module for a Solid State, X-band (9.5 GHz), Doppler, Dual Polarized meteorological radar system for the CASA student Test Bed is presented in this thesis. This Solid State ...
Development of 2d testbeds and implementation of helix antennas using frequency and time domain measurements for assessment of cwr technologies
(2012)
The contamination of underground systems causes serious detriment to the environment and can pose a serious threat to human health. The challenge of locating many common contaminants creates the need to develop technologies ...
Design of a leaky-wave antenna for 5G purposes using gap-waveguide technology
(2020-05-25)
A quasi-uniform leaky-wave antenna for 5G was designed at 39 GHz using the new holey EBG gap-waveguide structure. The antenna is designed for n260 band, with the
requirements that it is compact, low-cost and has high-power ...
Design and characterization of cavity-backed asymmetric annular ring slot antenna and UWB cavity-backed two-arm modified compound power-Archimedean slot spiral antenna for body centric wireless communications applications
(2015)
In this thesis, two types of slot antennas are studied, designed and characterized for the purpose of achieving Ultra-wideband (UWB) capabilities when in close proximity to the human body. The antennas are first designed ...
Vivaldi antenna array for a solid state space distributed amplifier
(2009)
This work reports the design of a Vivaldi antenna array for a space distributed solid state amplifier at X-Band and the specifications in the amplifier design. A tray configuration inside an over-moded waveguide is used. ...
Design and characterization of broad band and multi-band slot ring antennas
(2004)
In this thesis, the Design of Experiments technique is applied to characterize rectangular slot ring antennas in terms of their physical dimensions and relative permittivity of the substrate. Several 25 factorial designs ...
Characterization of log periodic folded slot antenna array
(2005)
This work studies the log-periodic folded-slot array (LPFSA) using Design of Experiments (DOE) techniques. The LPFSA impedance, gain and time-domain responses were analyzed and regression models were used to predict the ...
