A Novel Structure and Design Optimization of Compact Spline-Parameterized UWB Slot Antenna

Blog Article

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 turbo air m3f72-3-n obtain a considerable size reduction rate, the slot is parameterized using spline curves.All antenna dimensions are simultaneously adjusted using numerical optimization procedures.The fundamental bottleneck here is a high cost of the electromagnetic (EM) simulation model of the structure that includes (for reliability) an SMA connector.

Another problem is a large number of geometry parameters (nineteen).For the sake of computational efficiency, the optimization process is therefore performed using variable-fidelity EM simulations and surrogate-assisted algorithms.The optimization process is oriented towards explicit reduction of the antenna size and jerome brown jersey leads to a compact footprint of 199 mm2 as well as acceptable matching within the entire UWB band.The simulation results are validated using physical measurements of the fabricated antenna prototype.
