    摘要： A method for improving the efficiency of a solar heating system based on absorbing heat from solar radiation through the surface of an exposed tube to a liquid. The heat transfer device makes use of this fluid to transfer heat from the outside of the wall to the inside of the wall. The inside wall is then used to heat air that is passed over it, and that air is then used to heat up a heat storage system.

    摘要： A multi-polarized phased array antenna includes an element, a first feed line, a second feed line, a first phase shifter, and a second phase shifter. The element is fed with a first polarization signal at first and third angles, and a second polarization signal at second and fourth angles. One of the first polarization signal and second polarization signal is cancelled at a feed point in at least one of a first feed line and second feed line by operation of the first phase shifter, second phase shifter, first angle, second angle, third angle, and fourth angle. The first phase shifter provides a first 180° phase shift between the first and third angles, and the second phase shifter provides a second 180° phase shift between the second and fourth angles. A corresponding method of increasing isolation between polarizations in the multi-polarized phased array antenna is also provided.

    摘要： A multi-polarized scanning phased array antenna includes a plurality of elements, a first feed line operatively coupling the plurality of elements, a second feed line operatively coupling the plurality of elements, and a phase delay operatively coupled in at least one of the first feed line and the second feed line. The phase delay is configured to cancel a polarized signal associated with the multi-polarized scanning phased array antenna. A method of increasing isolation between polarizations in a multi-polarized scanning phased array antenna includes coupling a plurality of elements operatively with a first feed line, coupling the plurality of elements operatively with a second feed line, and coupling a phase delay operatively in at least one of the first feed line and the second feed line such that a polarized signal associated with the multi-polarized scanning phased array antenna is cancelled.
