Comb-shaped dipole antenna on transparent substrate

In order to satisfy the demand of huge data transmission, wireless communications, such as digital video broadcasting (DVB) and ultra wideband (UWB) systems, have oriented toward broadband development. We have designed a broadband comb-shaped dipole antenna fabricated on a transparent substrate for DVB/UHF broadcasting applications. The comb-shaped dipole, which utilizes the different current paths and strong coupling effect, leads to a wideband oscillation mechanism. The fashion and shape of the conducting strips of comb structures can be adjusted to achieve the required operating frequency band, radiation patterns, and impedance match. Since the width of the conducting strip can even be designed to micrometer or narrower sizes, beyond the resolving ability of vision, the antenna can be built on a transparent material such as Mylar or glass to form a low cost, wideband ´invisible antenna´.
