This paper presents, for the first time, a low cost, 60 GHz, RF front-end Tx/Rx integrated with a Yagi-Uda antenna array on organic Liquid Crystal Polymer substrate. The Tx/Rx module consists of a GaAs LNA, PA and a Single Pole Double Throw (SPDT) switch wirebonded on a single, multilayer substrate. The array was designed for operation at 60.6 GHz with a gain of 12.1 dBi. The radiation pattern measurements...
For the first time, a transmit-receive (TR), 64-element phased array fully driven by Silicon Germanium (SiGe) integrated circuits and implemented on organic substrates is demonstrated at 9.5GHz. The array was realized on a duroid and liquid crystal polymer substrate stack-up. The radiating elements are driven by SiGe-based TR modules and power amplifiers. Additionally, radio-frequency micro-electromechanical...
The use of an array of miniaturized elliptical substrate lenses or mini-lenses, combined with an array of printed antennas, is proposed for plasma imaging applications. Compared with its predecessor, the large hyper hemispherical lens, the new configuration demonstrates reduced sidelobe levels, minimal off-axis aberrations, increased RF bandwidth, and enhanced local oscillator coupling with substrate...
