Abstract. The project is aimed at the designing, based on a systematic approach to the design of antenna elements and systems, an algorithm for design of dual-band dipole antennas with non-traditional excitation. The ends-fed excitation technique, proposed in the work, makes it possible to space the central part of the substrate for placing additional radioelectronic components, and at the same time to reduce the electromagnetic interaction of the supply strips of the balun circuit. The proposed excitation technique allows designing new types of antenna, such as cardioid antenna, turnstile antenna, antenna array with principally different electrodynamic regimes. The parametric optimization algorithm for the thin-wire model, as well as the printed equivalent, is based on formal relationships for the input impedance and the generalized directivity function of the driver proposed. The corresponding closed-form expressions specify initial approximations of independent geometry parameters calculated for given central matching frequencies. The stated sequence of procedures allows, within the framework of a systematic approach, to determine the initial approximations of the geometric parameters of the driver. At subsequent design stages, the problem of pairing the driver and the matching-balun circuit is solved. Thus, the entire task is decomposed into independent computational blocks, simplifying and reducing computational costs.
Key words: end excitation type, dual-band exciter, matching, directionality, optimization.
