The application of Ku-band VSAT Systems to single layer hexagonal micro strip patch antenna is thoroughly simulated in this paper. The radiating elements in this antenna are composed of two triangular and one rectangular slots from the conventional micro strip patch antenna. These slots are engraved in the rectangular and triangular patch, joined together in two structures, and by single probe ...

When comparing documents images based on visual similarity it is difficult to determine the correct scale and features for document representation. We report on new form of multivariate granulometries based on rectangles of varying size and aspect ratio. These rectangular granulometries are used to probe the layout structure of document images, and the rectangular size distributions derived fro...

In this paper, a microstrip patch antenna is studied and the results are simulated using IE3D simulator with an operating frequency of 3 GHz. The conducting patch can take any shape but the preferred configurations are rectangular and circular since the other configurations are parameters. IE3D is a Moment of Method Simulator which solves the Maxwell’s Equations in an integral form through the ...

This work demonstrates the feasibility of using high intensity focused ultrasound (HIFU) for selective ablation of renal tissue through laparoscopic procedures. Two laparoscopic HIFU probe prototypes were developed and tested. Probe 1: It is a hand-held probe with no integrated ultrasound imaging capability. It consists of two focused rectangular HIFU piezoceramic crystals mounted on a stainles...

In this study, the near magnetic field shielding measurement method using a microstrip line is analyzed and compared with IEC 62333-2 standard for thin electromagnetic interference (EMI) sheets that are used to prevent or suppress noise coupling through numerical simulation. A comparison of as source generating circular loop probe presented in confirmed although strength was weak, it could gene...

This research quantitatively investigates fluid damping of MEMS and NEMS flexural resonators such as scanning probe and carbon nano-tube resonators, aiming to improve the quality factor prediction and therefore the resonator design. Fluid damping in beam-type resonators is most affected by resonant frequency, device dimensions and cross-sectional shape which are systematically examined within. ...

An analytic expression describing the complex voltage measured between the pickup points of a four-point probe, in contact with the surface of a half-space conductor, is derived. The driving current is assumed to be time harmonic. There are two contributions to the measured voltage. One arises from the potential drop due to electric current flowing in the conductor. The other arises from induct...

A novel fractal called Fractal Clover Leaf (FCL) is introduced and shown to have well miniaturization capabilities. The proposed patches are fed by L-shape probe to achieve wide bandwidth operation in PCS band. A numerical parametric study on the proposed antenna is presented. It is found that the antenna can attain more than 72% size reduction as well as 17% impedance bandwidth (VSWR<2), in co...

In this paper, the design of rectangular dielectric resonator antenna (RDRA) with coaxial probe and microstrip line feed arrangements and corresponding return loss vs. frequency characteristics and radiation performance in C-band of microwave frequencies using finite integration method (CST Microwave Studio) and verified by finite element method (Ansoft High Frequency Structure Simulator) are p...
