Sleeve antenna with ground wires

Pocklington's integral equation for a sleeve antenna with ground wires is formulated. By applying the Galerkin method to this equation, a sleeve antenna, a monopole antenna with ground wires, and a sleeve antenna with ground wires are analyzed, and numerical results for these antennas are compared with measured data. The sleeve antenna features the leakage current on the surface of the coaxial feeder, suppressed by a sperrtopf, but it is mismatched with the 50- Omega feeder. The monopole antenna with inclined ground wires may be adjusted to match the 50- Omega feeder, but the leakage current induced on the feeder cannot be neglected. It is found that the sleeve antenna with ground wires has the advantages of both antennas.<
