PROFESSIONAL EXPERIENCE:

RF Engineer

Confidential, Maine

Responsibilities:

Designed miniature wideband planar bow tie, log periodic and suspended or proximity coupled patch antenna along with narrow band PIFA, folded dipole and Spiral radiative antenna to operate in UHF range to interrogate multiple SAW sensor responses in harsh corrosive and very high temperature environment.
Designed wideband near field inductive coupled loop antenna to resonant by adding lumped component to achieve proper impedance match for interrogating differentially impedance matched multiple small sensor loop antennas.
Achieved successful wireless interrogation by using bended halfwave dipole or meandered line monopole antenna with proper ground technique inside an enclosed metal chamber whose dimension is less than quarter wavelength.
HFSS and ADS has been used to implement initial design concept of each antenna and RF front end circuit.
Test and debug software defined radio (SDR) system to acquire the signals from wireless sensors.
