This letter reports a microstrip mesh array antenna in a low temperature co-fired ceramic (LTCC) technology for 94-GHz applications. The microstrip mesh array antenna enlarges the system polarization diversity with the capability of being utilized to support the simultaneous reception in two orthogonal polarizations, as well as transmission in...

A designed microstrip grid array antenna at 94 GHz in a low-temperature co-fired ceramic (LTCC) technology was fabricated and measured. The designed and measured results are in good agreement. They show a 10-dB impedance bandwidth of 5.12 GHz from 90 GHz to 95.12 GHz (or 5.45% at 94 GHz), a maximal peak realized of 17.1 dBi with a 3-dB gain...

In this letter, we present a method to extract the scattering parameters of a microelectronic probe used to feed on-chip or in-package antennas at millimeter-wave frequencies.

A micro-electro-mechanical systems fabrication process has been developed to create self-assembled on-chip high efficiency antennas. The self-assembly creates out-of-plane antenna structures, which can have good radiation efficiency on low resistivity substrates. The structural material is SU-8 and the self-assembly curvatures are defined...

During the past years, various research teams developed 60 GHz chipset solutions, using both advanced CMOS [1] and BiCMOS [2] technologies. But for the 60 GHz market to flourish not only low cost RFICs are required, low cost antennas and packages are also key elements. Recently, low cost High Density Interconnect (HDI) organic technology has...
