The rapid growth of telecommunication gives rise to an ever-increasing demand for patch antennas with wide impedance bandwidth. The patch antenna invented by CityU is equipped with a pair of folded feed plates that serve as a wideband impedance matching device. It can achieve an impedance bandwidth .....

Conventional air-conditioning (AC) systems produce considerable amount of cold condensate as moist air is cooled below the dew point. The condensate is commonly drained resulting in thermal loss. The waste thermal energy can be recovered to increase the overall coefficient of performance (COP) by ci.....
