In this paper, one 5 × 5 antenna array are studied. In each array, one probe-fed circularly polarized (CP) microstrip patch antenna is placed at the center as the driven antenna and is gapped coupled to the remaining elements. It is investigated that CP performance of the patch can be proved by properly arranging these parasitic elements. The driven patch is a perturbed square one with two diag...

This paper concerns with a new class of adaptive gain-scheduled H∞ control of linear parametervarying (LPV) systems with time-delayed elements. The plants in this manuscript are assumed to be polytopic LPV systems which have time-delayed components, but the scheduled parameters and time-delayed elements in those plants are not known a priori, and thus, the conventional gain-scheduled control st...

A novel CPW-fed antenna capable of triple-band operation for WLAN/WiMAX applications is presented and investigated in this paper. The proposed antenna simply consists of three elements viz. folded open stub, L-shaped open stub, and Y-shaped resonator. By using the three elements, triple-band antenna operating at 2.5/3.5/5.5 GHz can be achieved. The antenna impedance bandwidths for |S11| ≤ −10 d...

A micro strip-fed printed bow-tie antenna is presented inorder to achieve wide bandwidth, high gain, and size reduction. A comparisonbetween the bow-tie and the quasi-Yagi (dipole and director)antennas shows that the bow-tie antenna has a wider bandwidth, highergain, lower front-to-back ratio, lower crosspolarization level, andsmaller size. Two-element arrays are designed and their characterist...

Preliminary communication In this paper a fundamental mathematical model (algorithm) for determination of condition of induction machine as well as the simulation procedure for measurement of certain values in program MATLAB has been presented. A scheme of measuring system and results of simulation application are presented on output lists. Thus, measuring system gradually develops and improves...

"Virtual reality" (VR) describes an "interactive computer environment": "A computer generated an image; a display system presented the sensory information; and a tracker fed back the user's position or orientation in order to update the image. The elements combined to substitute sense data from the natural world with sense data about an imaginary world that changed in response to the user's act...
