A transceiver MIMIC (millimeter wave monolithic integrated circuit) with four antenna ports functionality for 55 to 65 GHz wireless multimedia applications has been developed. The chip has been realized using 100 nm gatelength metamorphic InAlAs / InGaAs HEMT (high electron mobility transistor) technology on GaAs substrate together with GCPW (grounded(More)
This letter describes a compact broadband-stacked microstrip array antenna with a small novel lens for 60-GHz applications. The proposed antenna consists of 2/spl times/2 stacked patch elements using a multilayer RT/Duroid substrate. The microstrip array antenna achieves a gain of 10dB. By adding a small, novel eggcup-type of lens to the antenna, a gain of(More)
A front-end MIMIC (millimeter wave monolithic integrated circuit) with a 4:2 MUX/DEMUX (multiplexer / demultiplexer) functionality for 60 GHz transceiver with multiple antennas has been developed. The chip has been realized using 100 nm gatelength metamorphic InAlAs / InGaAs HEMT (high electron mobility transistor) technology on GaAs substrate together with(More)
