ABSTRACT:
An apparatus includes a monopole extending substantially along an axis that may be vertical. However, the monopole may have a loop portion that deviates from the axis. Further, the apparatus includes multiple conductive elements, each having a substantially linear first segment that is coupled to the monopole. The first segments may be coplanar and/or perpendicular to the axis. Each of the conductive elements may further include a second segment that is substantially parallel to the axis. One or more of these segments may be connected to a ground potential. Also, the conductive elements may each include a third segment having a loop pattern.
