This study investigates a particular type of ground plane modifications in ultra‐wideband (UWB) antennas and the effect they have on achievable amount of miniaturisation of the structure at hand. The focus is on n‐section rectangular slits below the feeding line. The authors analyse possible size reduction as a function of the number n of slit sections. In order to ensure that the minimum antenna footprint is obtained in each case, rigorous numerical optimisation of all antenna parameters has been carried out. The optimisation process is constrained to guarantee that the antenna exhibits acceptable in‐band matching at the level of −10 dB. For the sake of generality, the study has been performed using a benchmark set of four representative UWB monopoles. The results clearly indicate a significant advantage of increasing the number of degrees of freedom of the ground plane slit but also the saturation effect, i.e. decreasing advantages of introducing additional slit sections beyond a certain value of n. The average amount of miniaturisation for n = 5 versus n = 1 is around 40%. For selected designs, numerical results have been validated experimentally.

Introducing ground plane modifications is a popular approach in the design of compact UWB antennas. Yet, specific topological alterations are normally reported on case to case basis without thorough investigations concerning their general suitability for antenna miniaturization. In particular, detailed performance comparison of different ground plane modifications is lacking in the literature. In this article, the effect of selected ground plane modifications on achievable miniaturization rate is considered based on a set of four UWB antennas. EM‐driven optimization is carried out to minimize the antenna footprints while maintaining acceptable matching within the UWB frequency range. In each case, all geometry parameters of the respective structures are utilized in the design process. For the sake of fair comparison, all antennas are implemented on the same dielectric substrate. Our results indicate a clear performance pattern, here, an advantage of the elliptical ground plane slit below the feed line over the rectangular one (average size reduction ratio of 26% versus 19% across the benchmark set). Our conjectures are confirmed by physical measurements of the fabricated antenna prototypes.

In this work, a printed ultra-wideband (UWB) antenna has been proposed exhibiting band notch characteristics. The proposed design covers the entire UWB band except for the 3.5 GHz band providing the band notch for the WiMAX band. This design consists of two-quarter elliptical patches placed symmetrically over the FR4 substrate. The elliptical shape of the patch is responsible for the UWB band achieved. The slot has been created on the optimized patch area to achieve the desired characteristics providing a notch for the WiMAX band. The slot in the patch is so perfectly designed that it gives the patch a perfect shape of butterfly wings. After designing, the proposed antenna was simulated and then fabricated. The fabricated and simulated results are in close agreement with each other which shows, the proposed UWB antenna is good enough for biomedical applications.
