    Maintaining small physical dimensions of antenna structures is an important consideration for contemporary wireless communication systems. Typically, antenna miniaturization is achieved through various topological modifications of the basic antenna ...
  • Bekasiewicz, Adrian; Koziel, Slawomir (Polish Academy of Sciences, 2016-12-01)
    In this paper, a novel structure of a compact UWB slot antenna and its design optimization procedure has been presented. In order to achieve a sufficient number of degrees of freedom necessary to obtain a considerable size reduction rate, the slot is ...
  • Koziel, Slawomir; Bekasiewicz, Adrian (Walter de Gruyter GmbH, 2016-12-13)
    Re-design of a given antenna structure for various substrates is a practically important issue yet non trivial, particularly for wideband and ultra-wideband antennas. In this work, a technique for expedited redesign of ultra-wideband antennas for various ...
  • Koziel, Slawomir; Bekasiewicz, Adrian (Walter de Gruyter GmbH, 2015-09-23)
    This paper addresses computationally feasible multi-objective optimization of antenna structures. We review two recent techniques that utilize the multi-objective evolutionary algorithm (MOEA) working with fast antenna replacement models (surrogates) ...
