Experience
Sr. Radar Systems Engineer, 01/2012 to 01/2013 Morrison Hershfield – Salt Lake City, UT,
Working in a team setting upgraded existing legacy phased array antenna system capable in a desert environment of surveying high altitude ballistic missiles.
White paper recommendations for low observables implemented Attended government meetings to recommend component hardware improvements Wrote white papers to inform the government of antenna system vulnerabilities Participated in radar legacy system upgrade contractor bid proposals.
Senior Electrical Engineer, 01/2007 to 01/2012 Otterbox – Co, CO,
Antenna hardware design).
Designed meander line antenna for commercial aircraft communications using HFSS.
Designed Low-cost Ku-Ka band FSS miniaturized antennas using HFSS and PCAAD.
Designed wide-band slots and mesas as waveguide feeds to parabolic dishes, BAVA's and patches.
Jr. Phased Array Antenna Hardware Design Engineer, 01/1997 to 01/2007 United Technologies Corporation Norden Systems – City, STATE,
Built & designed and tested Ku- X band JSTARS phased array antenna for GTI, MTI, and SAR Designed dual-mode feed network to increase channel capacity across frequency bandwidth and provide composite beam coverage for microwave signals of the same polarization oriented orthogonal to one another Performed studies on ferrite phase shifters and pin diodes Made recommendations to use ferrite phase shifters and incorporate a unique 32-bit design Designed cross-guide directional couplers and magic-tee waveguide to support signal splitting in transmit and receive mode Jessica.
Claire Page - 2 - Designed and built prototype sub array units of a stick antenna supported by a corporate feed network.
Branch sticks were a replacement for parabolic reflector antennas.
Branch sticks were resonant arrays of longitudinal shunt slots in waveguide fed by a resonant main feed.
Designed a hybrid monopulse feed network to perform sum and difference patterns in azimuth and elevation, while a corporate feed network excited all the cross-guide feeds, since each quadrant had its own feed port.
Performed Taylor n-bar and Dolph-Chebyshev array synthesis to analyze sidelobe performance given power and phase requirements to suppress grating lobes and edge effects, so the slot array waveguide could fit in a long canoe shaped radome.
Designed electronic steerable stick array to tilt by 120 degrees on both sides of the aircraft bottom creating a travelling wave antenna since the array rotated in azimuth, beam squint was reduced by my hybrid design.
Designed cross-guide directional couplers with reduced mutual coupling and edge effects, with the assistance of precise fabrication.
Assisted in the invention of a BITE coupler, "Built in Test Equipment" unit that performed a rapid self-test/phase correcting adaptive feedback loop that was used on the moving aircraft.
Extremely low level sidelobes of a 1-D fixed planar array, stick antenna quadrants, demanded tight aperture phase tolerances, which required periodic testing and phase correcting of the array elements to compensate for phase errors.
Jr. Phased Array Antenna Hardware Design Engineer, 01/1987 to 01/1997 Texas Instruments Research And Development – City, STATE,
Designed, built, and tested, C-X band phased array hardware components.
Designed stripline feed to Vivaldi array.
Goal was to design and build 2:1 and 5:1 frequency bandwidth conformal phased array Performed a research study on a planar array cavity to slot line to antenna transition.
Invented a resonant cavity shunted circuit model that smoothly channeled the microwaves to the slot line-antenna transition without surface wave reflections.
Eliminated past designs with resistive terminating pins to mitigate surface waves along pc board and hybrid TE, TM modes building up in the cavity utilized network analyzer and CAD tools to test prototypes.
Designed tapered and bent stripline feed elements for spacing, impedance matching, and VSWR performance.
Performed antenna study for planar array.
Analyzed network analyzer data for impedance matching and VSWR characteristics.
Aperture spill-over was considered.
Rhombic antenna was too difficult to impedance match, and keep the reflections back to the feed suppressed.
The tapered horn antenna (Vivaldi antenna) was the antenna I recommended.
It was also, easier and reliable in fabricating many prototype pieces to be configured in an egg carton type of configuration.
Performed test for sidelobes using a near-field probe range, and assisted in building a Wheeler Simulator to measure sidelobes in an infinite array environment.
Microwave Antenna Design Engineer, 01/1980 to 01/1987 Adams Russell Inc – City, STATE,
Designed, built, and tested Ku-X band double ridged to quad-ridged horn antennas.
Designed, and built, log periodic spiral arm antennas for FIRPA backpacks, Army field antennas Jessica.
Performed lab metrology in an anechoic chamber with standard gain horn antenna.
Utilized roof top outdoor test range, and indoor mini ranges.
Machine shop cut out prototype test pieces that we put together with silver dope epoxy glue and tested.
RF Antenna Engineer, 01/1975 to 01/1980 GTE Sylvania – City, STATE,
Performed nuclear hardness and survivability studies for antennas buried under the earth.
Initiated a study on antenna burial depth including, skin depth and loss tangent of earth layers, utilizing constitutive relations in Maxwell equations.
Studies by Dr.
Janis Galesj and Guy-Hasserjian estimated wide frequency band transmission VLF to HF with stable impedance characteristics would require a dipole antenna of at least 200 meters in length buried under the earth.
Assisted in the testing of antennas buried in the Salt flats of Utah, low rainfall, stable ground conductivity and resistance.
Later we tested small scale model antennas buried in Waltham, MA soil.
We were seeking omnidirectional patterns.
Assisted in taking test measurements with HP spectrum analyzer.
Learned how to write method of moments code for center fed buried dipole antennas using DEC time sharing PDP 11 computer.
