In this communication, an odd and even mode compression method is proposed to extend the bandwidth of conventional thin dipole antennas while maintaining a stable omnidirectional radiation pattern. Wide achieved by simultaneously exciting compressing 1<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup>-order (odd) 2<sup xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup>-order (even) modes, enabling their combination.

A model based on forward and inverse problems of pipe transverse crack detection is studied. First, Rayleigh beam elements Daubechies wavelet are constructed to solve the problem. The first three frequencies influencing functions normalised location size approximated by means surface-fitting techniques. Then, measured natural employed as inputs functions. genetic algorithm used identify size, solving smallest sample points difference between outputs structural vibration model. Experimental...
In this article, a novel direct geometric algorithm for worst-case error analysis of six-port reflectometer is proposed. Due to the inevitable power measurement uncertainty, shows an inherent deviation that can be represented as irregular area based on classical geometrical theory. The previous approximates boundary with straight lines and utilizes several special points in comparison. Without approximation, distribution directly obtained proposed algorithm. After traversing all points,...
In this paper, a novel dual-polarized capsule antenna is designed. The printed on circular substrate with superstrate to miniaturize the antenna, and located at upper end of capsule. dual-polarization capability achieved by exciting pair degenerate modes meandered ring-slot using two inductive coupling elements (ICEs). designed for use in ISM (Industrial, Scientific, Medical) band 2.45 GHz. Since adopts orthogonal modes, there relatively high isolation between ports. To verify proposed...
4-DOF asymmetric parallel manipulator 2TPS /2TPR is researched in this paper. Firstly, the structure of described detail. Optimized design variables and constraints are sure. Then multi-objective optimization built by flexibility workspace structure. Finally, 2TPS/2TPR based on GA. The optimal size combination got.
