<p>[Problem] To implement high antenna gain with a miniaturized simple configuration, as a UHF wide frequency band antenna, for example, which is usable in a vehicle-mounted device, etc. [Solution] An inner conductor (7) of one end of adjacent coaxial cables (CL1-CL3) connects with another outer conductor (5), an outer conductor (5) of one end connects with another end of the inner conductor (7), and one inner conductor (7) of the coaxial cable (CL3) which is second from the end stage connects with another outer conductor (5) of a coaxial cable (CL4) of the end stage. A plurality of coaxial cables (CL1-CL4) is thus positioned in a column. The length (L2) of each of the coaxial cables (CL1-Cl4) is effectively 1/4 the used wavelength ?.</p> |
