PURPOSE: To form the projecting element antenna of the array antenna, which is spread while connecting one terminal to a fixed radio equipment, into a coaxial cable (with the same function as a linear antenna).
CONSTITUTION: Plural element antennas 7 arranged at prescribed intervals with a coaxial cable 8 as a feeder line are composed of antenna elements eliminating one part of the outside conductor of the coaxial cable over a 1/4 wavelength and serially connected by a coaxial connector 13. Otherwise, the respective plural antenna elements are connected by the coaxial connector forming the two coaxial cables having the length of the 1/4 wavelength so as to cross connect inside and outside conductors, and these antenna elements are serially connected.
