Abstract
This paper presents a novel multi-objective naked mole-rat (MONMR) algorithm to optimize two printed monopole patch antenna structures for ultrawideband (UWB) applications. The design includes basic-ultrawideband and triple band-notch characteristic antennas. The performance of MONMR is evaluated for two objectives: minimize pass-band signal reflection and maximize the gain of the antenna. In resultant, MONMR provided multiple optimum antenna designs instead of a single antenna design by mapping solutions to the Pareto-front (PF) boundary in the objective space. The simulated results matched with the experimental results and hence MONMR has proved to be an effective approach in the field of electromagnetics. Moreover, the obtained PF designs are better than the reported UWB antennas in terms of the gain and reflection coefficient.
