Abstract
With the recent increase in the demand for an wireless communications, new technologies is anticipated to appear to provide high quality and high capacity services for all users, operators, and manufacturers. The array antenna technique using braun antenna is steadily proposed as one of the technologies to realize this future communication system. The antenna that applied the array technique of the braun antenna is known as smart antenna. Smart antenna is the intelligent antenna system that can react to the given signal environment and change its array patterns automatically. It is based on the array technique that combines signals received from antenna elements arrayed linear, circular, and planar antennas.
Despite there is various kind of antenna, there are problems such as TVI, BCI, space, occupant group (apartment administration), noise problem etc. in antenna establishment in downtown area. Accordingly, establishment is emphasized necessity of easy and performance is excellent antenna.
In this paper, in order to solve these problems, we experimented some conformity methods using manufacture antenna that Brown proposed. Impedance matching of the Brown antenna is existent method by length control of a branch's angle and feeder. However, certified even if depend in control of length of duplicator and branch's angle experimentally that impedance matching is available
As a result, in case of the proposed method that is impedance matching of brown antenna is fixed height with rooftop of building, matching is possible independently with feeder's length. Therefore, when establish brown antenna, expected that can be used usefully.
