dc.description.abstract | A 1 x 3 array of 296-GHz complementary metal oxide semiconductor concurrent transceiver pixels incorporating a low noise amplifier, a differential gain stage, and a double-balanced I/Q mixer and a quadrature local oscillator generator for extraction of baseband signal amplitude and phase in addition to the RF section in an area of similar to (lambda/2)(2) is demonstrated. The effective isotropic radiated power of the array is similar to-6 dBm and the minimum double sideband receiver pixel noise figure is similar to 48 dB. An E-shaped patch antenna is used to broaden the antenna bandwidth (14-GHz -10-dB |S-11| bandwidth). Using a pair of these arrays, lens-less short-range reflection mode imaging of a target similar to 1 cm away through a cardboard covering is demonstrated. The phase and amplitude outputs enable a synthetic increase of the effective aperture to the scan area from the pixel area for improved image quality and resolution. The use of phase combining for the 1 x 3 transmitter array also improves the isolation between the pair for reflection-mode imaging which limits the stand-off range by similar to 10 dB (to similar to 70 dB) compared to that when a pair of single pixels with a conductive wall is used. | - |
