Patent ID: 6980172

Claim:
A multi-band cable antenna comprising: a dielectric substrate, as a nonconductive dielectric having a predetermined dielectric constant, with a plurality of conductive microstrips formed on top and bottom sides of the dielectric substrate, for inducing a resonance in the multi-band; and signal transfer means including first and second conductors for signal transfer, which are electrically separated from each other by a layer of insulator, the first conductor for signal transfer configured to be short-circuited with one of microstrips formed on the top side of the dielectric substrate, wherein the dielectric substrate further includes an upper and lower short-circuited conductor for short-circuiting the second conductor for signal transfer on the signal transfer means with one of the microstrips formed on the bottom side of the dielectric substrate, and wherein the upper and lower short-circuit conductor and the microstrips formed on the bottom side circuit-shorted with the second conductor of signal transfer are electrically grounded.
