Synthetic aperture technique has the potential to meet the spatial resolution requirement of passive microwave remote sensing. In order to verify the theory of aperture synthesis at low expense, it is desirable to use only two receivers channel and one digital correlator and to measure all the baselines successively. Considering this, a one-dimensional prototype of aperture synthesis system at Ku...
For the first time, a UNII band monolithic transceiver with two on-chip antennas has been demonstrated. The complete chip, sized 3 mm2, is the smallest reported for such a configuration. The antenna on the TX side performs double duty by providing the inductance to the VCO resonant tank. On the other hand, the RX side antenna has been conjugate matched to the LNA. Through a co-design strategy, the...
This letter presents the smallest reported 5 GHz receiver chip (1.3 mm2) with an on-chip antenna in standard 0.13 mum CMOS process. The miniaturization is achieved by placing the circuits inside a meandered antenna. The on-chip antenna is conjugately matched to the low noise amplifier (LNA) over a wide frequency range. The design methodology for co-design of the on-chip antenna and LNA is described...
The on-chip antenna concept is a practical solution to compact, small size and low cost transceivers for short range wireless applications like RFID tags and biomedical sensor data transmitters. Here we present a miniature on-chip antenna design in a 0.13 mum CMOS process which also serves as the inductor. The optimized on-chip inductor/antenna has a Q of 9.2, inductance of 2.0 nH and an omni-directional...
