摘要： A power regeneration device includes an extraction unit and a high frequency-to-DC converter. The extraction unit is provided on a transmission path. The transmission path is provided for transmitting a high-frequency wave from a high-frequency wave source to a high-frequency load. The extraction unit extracts a reflected high-frequency wave generated by reflecting the high-frequency wave from the high-frequency load. The high frequency-to-DC converter converts the reflected high-frequency wave extracted by the extraction unit into DC power.

摘要： An omnidirectional vertical polarization antenna is configured of monopole antennas, the number of which is k (k≧3), disposed on a circumference of a circle at equal spaces. An omnidirectional horizontal polarization antenna is configured of first to m-th omnidirectional antennas stacked in m (m≧2) layers in a first direction perpendicular to a reflector, and each of the first to m-th omnidirectional antennas is configured of half-wave dipole antennas, the number of which is n. The half-wave dipole antennas, the number of which is n (n≧3), configuring each of the first to m-th omnidirectional antennas are respectively configured of arc-shaped conductive bodies, and disposed, at equal spaces, on each of circumferences of circles, the number of which is m, having different diameters, when viewed from a direction opposite to the first direction. The first to m-th omnidirectional antennas are stacked from the reflector in the first direction. Accordingly, there is provided a dual polarization antenna using omnidirectional antennas, achieving omnidirectivity as the directivity in the horizontal plane with less deviation of directivity than before, by using the half-wave dipole antennas.
