SPHERICAL MONOPOLE ANTENNA

摘要

Various examples are provided for spherical monopole antennas. In one example, among others, a spherical monopole antenna includes a spherical conductor on a first side of a substrate and a ground plane disposed on the substrate. The spherical conductor is electrically coupled to a connector via a tapered feeding line and the ground plane surrounds at least a portion of the connector on the second side of the substrate. In another example, among others, a method includes forming a tapered mold in a die layer disposed on a first side of a substrate, filling the tapered mold with a conductive paste, and disposing a spherical conductor on a large end of the tapered mold. The conductive paste is in contact with a signal line extending through the substrate into a small end of the tapered mold and in contact with the spherical conductor.
