چکیده | ||
In this paper a novel method for computing the radiation pattern and also the input impedance of a planar rectangular micro-strip antenna array with consideration of mutual coupling and mutual impedance is presented. Each two triangles with a common edge make an Edge element or RWG. Any such edge element is considered as an infinitesimal dipole. The electrical currents over each dipole can be calculated by solving an electric field integral equation (EFIE), using the method of moments. Using the resulting surface currents and considering the mutual coupling effect between the elements, the radiation pattern of the whole array is obtained employing a new method, which we call it “active element pattern based on RWG edge element”. Moreover, using the above mentioned model for the edge elements and also considering the mutual impedance between the elements, the input impedance of the array is now calculated. | ||
