The well-known limits on the radiation Q of electrically-small antennas do not lead to a straightforward, rigorous computation of wideband impedance matching limits, especially when higher-order spherical modes are used and higher-order tuning networks are permitted. Fano's formulation of the wideband matching of arbitrary impedances does provide a rigorous solution, and has been previously applied to the lowest-order (TM01 or TE01) mode. In this paper we apply Fano's theory to higher-order spherical modes. Graphs of numerical limits on high-pass and band-pass tuning versus size are presented. [ABSTRACT FROM AUTHOR] |
