PLANAR ANTENNAS FOR MILLIMETER AND SUBMILLIMETER-WAVE APPLICATIONS
Most of
the antenna work in this area was done between 1988-1996 by Eleftheriades,
Ali-Ahmad, Ling, Gearhart, Kormanyos, Filipovic and Raman. This
research, together with Filipovic on the Dielectric Lens Antennas,
pushed integrated antennas to their highest performance at mm-wave
and submillimeter-wave frequencies. The following papers summarize
the effort at the University of Michigan.

in this section is based on integrated horn antennas (Ali-Ahmad),
double-slot antennas (Gearhart, Filipovic, Gauthier), log-periodic
antennas (Kormanyos, Gearhart) and the double-folded slot antenna
(Mollenkopf). The detector is a Schottky diode, either built at
the University of Michigan or at the University of Virginia, or
a MMIC amplifier followed by a Schottky diode. The following papers

about dielectric lens antennas and were afraid to ask. This work
is unique, and has set the stage for many a Ph.D. thesis around
the world (Holland, Canada, Japan, U.S., France, Germany). Download

IV.
94 GHZ MONOPULSE RECEIVERS
These two
papers summarize the work of Ling and Raman on the development
of planar monopulse receivers. The idea is based on IF processing
of the 4 signals from the monopulse antenna, that is, downconvert
the signal from 94 GHz to 2-4 GHz, and then do the accurate sum
and difference processing at the IF. The work of Raman resulted
in a state-of-the-art monopulse tracking system with a 2 GHz bandwidth
and a tracking null which is better than 30 dB. The system noise
figure was around 13 dB at 94 GHz. The wideband IF monompulse
network was developed by Scott Barker, and showed a bandwidth
of more than one octave.

PLANAR MIXERS AND MULTIPLIERS
This section
represent some of the work which has been done on planar mixers
and multiplier in the TICS group. Raman achieved a 6-7 dB SSB
conversion loss at 90-100 GHz for a subharmonic mixer with only
2-3 mW of LO power, and Lee and Chi worked on planar doped barrier
diodes and on biased back-to-back subhamornic diodes for low LO
power applications. Also, Kormanyos developed an extremely wideband
26-260 GHz subharmonic mixer with a conversion loss of around
20 dB at 200 GHz.
The work on planar multipliers represent some novel high performance multipliers for the microwave and mm-wave frequency range.

QUASI-OPTICAL OSCILLATORS AND AMPLIFIERS:
(HIGHEST FREQUENCY HEMT OSCILLATOR IN THE WORLD - 213 GHz!!)
Millimeter-wave
quasi-optical amplifiers and oscillators have also been developed
in the TICS group by Kormanyos, Budka, and Chi. The amplifier
is the highest frequency quasi-optical amplifier known-to-date,
and the oscillator is still, 6 years later, the highest frequency
HEMT oscillator ever manufactured (quasi-optical or circuits).
This work was done in conjunction with Hughes Research Labs, Malibu,
CA. Download the papers and enjoy reading them. The w-band quasi-optical
amplifier is still the highest frequency Q.O. amplifier built
to date.

NEAR-FIELD IMAGING USING MODULATED SCATTERING
This is
the work of Tom Budka who developed a micromachined modulated
scattering probe on a silicon substrate, and used it in near-field
circuit and antenna measurements from 1-18 GHz on Silicon, GaAs,
Teflon and ceramic substrates. He also developed a wideband 1-18
GHz quadrature demodulation circuit in order to get the phase
of the modulated scattering return. Too bad that this work was
not continued after Tom graduated in 1995, since it is quite interesting
and innovative. If you download the papers, you will find some
beautiful pictures of fields over circuits, filters and amplifiers.
