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 ...
Design of dual polarized antenna array for x band off-the-grid casa otg radar
(2012)
The design of a dual polarized antenna array operating at the center frequency of 9.4 GHz is presented in this thesis. A 2X2 dual polarized antenna sub array is designed on a multilayered structure for operation at 9.4GHz. ...
Design of V-Band substrate integrated waveguide fed aperture coupled microstrip patch arrays with circular polarization and parasitic patch for off-body communications in body centric wireless networks
(2017-05)
This work presents the design of a multi-layer radiating element and a multi-layer 2x2 array for use in 60 GHz body centric wireless networks. The antenna designed operates with an impedance bandwidth of 11.6%, from 57 to ...
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 ...
