摘要： An antenna-integrated strip line cable with which it is possible to improve the performance of a high-frequency appliance such as a portable telephone without making the appliance larger. An antenna-integrated strip line cable 1 is made up of a transmission line part 2, an antenna part 3 and a counterpoise 4. The transmission line part 2 is made up of two conductors 21, 22 disposed in parallel, insulators 23, 24 having plasticity or flexibility disposed between these two conductors 21, 22, and a central conductor 25 disposed between the insulators 23, 24 centrally in the width direction thereof. Wide-pattern impedance matching circuits 26a, 26b are provided in the central conductor 25. The antenna part 3 has portions of the insulator 24 and the central conductor 25 extending from the transmission line part 2. The counterpoise 4 has portions of the insulator 23 and the conductor 21 extending from the transmission line part 2. The counterpoise 4 is perpendicular to the antenna part 3 and the length of the counterpoise 4 is about one-fourth of the wavelength .lambda. of the frequency used. Some benefits of this novel construction are that the number of parts is reduced, the work of connecting a coaxial cable to an antenna is made unnecessary, the counterpoise reduces directivity of the antenna part, the antenna is tough, and it is not necessary to provide an impedance matching circuit externally.
