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 ...
Dual polarized microstrip antenna array for the off-the-grid radar
(2007)
The design and development of a linear antenna array operating at center frequency of 9.5 GHz is presented in this thesis. A 12 patch center-fed array composed of sub-arrays of series fed antenna array conformed by 6 ...
Tunable slot-ring antenna using varactors
(2003)
A dual mode rectangular slot-ring antenna fed with a coplanar waveguide transmission line was tuned over a band of frequencies using varactors. The analysis demonstrated that when varactors are attached to the side slots ...
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 ...
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 ...
Electromagnetic modeling of laboratory-scale 2d soil-bed setup
(2009)
This work presents the development of electromagnetic model for the laboratory 2-D Soil-Bed setup, which was developed at the Civil Engineering Department of the University of Puerto Rico, Mayaguez, to verify the posibility ...
Characterization of cavity-backed folded slot antennas
(2009)
In this thesis, two Cavity-Backed Folded-Slot Antennas (CBFSA’s) are characterized through the Design Of Experiments technique (DOE) to study the influence that the Folded-Slot Antennas (FSA) and cavity dimensions of each ...
