Abstract: A connection structure which electrically connects a connection terminal of an antenna element mounted on a mounting plate to a connection terminal of a coaxial cable connector mounted on the mounting plate, includes a plate-shaped electric connection member which includes an element connection end part electrically connected to the connection terminal of the antenna element and a cable connector connection end part extending away from the element connection end part and having a tapered shape. The connection structure further includes a bar-shaped electric connection member which extends along the cable connector connection end part of the plate-shaped electric connection member and which is electrically connected to the cable connector connection end part. Both the cable connector connection end part of the plate-shaped electric connection member and the bar-shaped electric connection member are electrically connected to the connection terminal of the coaxial cable connector.

Abstract: A phase correction apparatus comprising a storing means configured to store a phase correction value associated with each of a plurality of transmission antennas in which the phase correction value is calculated according to an electrical length of a signal path extending from a signal generator generating a transmission signal to the transmission antenna, and correction means configured to correct a phase of the transmission signal to be supplied from the signal generator to each transmission antenna according to the phase correction value for the transmission antenna stored in the storing means.
