This work presents four types of broadband compound antennas. The antennas are a combination of an electric dipole and small square or circular loops. The feeding of the electric dipole only is realized. The input impedance, reflection coefficient, and gain of the antennas with different geometries are analyzed numerically using the method of moments (MoM). It is shown that for the level of the reflection coefficient |Γ| < −10 dB, 80% to 90% bandwidth can theoretically be achieved for the proposed antennas. © 2005 Wiley Periodicals, Inc.
