In the paper, a concept and design procedure of a novel compact MIMO slot antenna is presented. In order to achieve a better filling of available space, individual antennas are constrained to a triangular shape and optimized for a reduced size. The MIMO structure is then assembled using the two of previously designed antennas in orthogonal arrangement. Surrogate-assisted numerical optimization involving...
In this paper, a structure and computationally-efficient simulation-driven design closure of spline-parameterized UWB monopole antenna has been presented. We start from a reference design which is a conventional monopole antenna with rectangular radiator and L-shaped ground plane stub. The antenna geometry is then modified by parameterizing the ground plane using splines. This introduces additional...
In this work, a novel structure and design optimization procedure of a miniaturized ultra-wideband (UWB) slot antenna is presented. A very small footprint of the structure (161 mm2) has been achieved by introducing sufficient number of degrees of freedom, including the parameterized multi-section slot and a multi-section load of the feed line, as well as efficient numerical optimization of all geometry...
In this paper, a novel structure of a compact UWB slot antenna is presented along with a simulation-driven design optimization algorithm for adjusting geometry parameters of the device. Our primary objective is to obtain small footprint of the structure while maintaining its acceptable electrical performance. It is achieved by introducing sufficiently large number of geometry degrees of freedom, including...
A structure and design optimization procedure of a compact UWB slot antenna is presented. Small size of the antenna and its good electrical performance is achieved by introducing sufficiently large number of geometry degrees of freedom, including a stepped-impedance feed line and a meandered slot with parameterized dimensions. All dimensions are simultaneously adjusted using automated EM-simulation-driven...
In this letter, a surrogate-assisted optimization procedure for fast design of compact patch antennas with enhanced bandwidth is presented. The procedure aims at addressing a fundamental challenge of the design of antenna structures with complex topologies, which is simultaneous adjustment of numerous geometry parameters. The latter is necessary in order to find a truly optimum design and cannot be...
In this work, a structure of a compact ultra-wideband (UWB) monopole antenna implementing an upper WLAN band-notch, as well as its expedited design optimization procedure, are described. The band-notch is realized using meander-shaped slots in the radiation patch. For the sake of computational efficiency, the design procedure exploits variable-fidelity electromagnetic (EM) simulations as well as adjustment...
A novel structure concept of a compact UWB monopole antenna is introduced together with a low-cost design optimization procedure. Reduced footprint is achieved by introduction of a protruded ground plane for current path increase and a matching transformer to ensure wideband impedance matching. All geometrical parameters of the structure are optimized simultaneously by means of surrogate based optimization...
