A microstrip patch antenna is a type of planar antenna commonly used in wireless communication systems. It consists of a metallic patch on a grounded substrate and operates efficiently at microwave ...

A novel multi-band end-fire antenna array was designed, fabricated, and characterized. Analytical calculations were carried out to determine the critical antenna dimensions and the design was ...

Abstract: A simple method for rectangular array pattern synthesis, which combines convolution of two perpendicular linear arrays with orthogonal approach for each linear array synthesis, is proposed.

Visualizing antenna patterns on a map can be helpful in design—this latest blog post from Rick Gentile discusses several methods on how to do that via MATLAB. I have covered many aspects of modeling ...

A matrix is a rectangular array of numbers. A random matrix can be compared to a Sudoku filled with random numbers. Matrices are part of the equations governing the movements of the particles. In a ...

Abstract: Resistivity measurements made with a four-point probe on a sample having at least one of its dimensions small (i. e., of the order of the spacing between the points of the probe or smaller) ...
