摘要： A transmission system includes: an antenna; a control device including an RF circuit which transmits a first signal for controlling a radio wave to be outputted from the antenna and an external power supply which supplies direct current to the antenna; and a first transmission path which connects the antenna and the control device, and is used in transmission of the first signal and supplying of the direct current to the antenna.

摘要： An antenna unit includes a plate-shaped dielectric substrate, as well as an antenna element and a stub element. The dielectric substrate has a first edge extending along a longitudinal direction of the dielectric substrate and a second edge extending along the longitudinal direction of the dielectric substrate, and the second edge is opposite to the first edge. The antenna element is disposed along the longitudinal direction of the dielectric substrate. The Antenna element has a first end containing a feedpoint and a second end containing an open end. The stub element is disposed between a section of the antenna element having a predetermined length containing the first end of the antenna element and the first edge of the dielectric substrate along the longitudinal direction of the dielectric substrate. The stub element has a first end connected to a reference potential and a second end containing an open end.

摘要： An antenna unit includes a conductive ground plate, a first antenna element, and a second antenna element. The first antenna element includes a first end connected to a feedpoint and a second end containing an open end. A part of the first antenna element is disposed along the conductive ground plate. The second antenna element branches off the first antenna element at a branch point on the first antenna element. The second antenna element is disposed between the part of the first antenna element disposed along the conductive ground plate and the conductive ground plate. The first antenna element resonates at a first frequency. The second antenna element and a segment between the first end and the branch point of the first antenna element resonate at a second frequency that is higher than the first frequency.
