PROJECT TITLE :

Efficient Radiation Antenna Modeling via Orthogonal Matching Pursuit in Terms of Infinitesimal Dipoles

ABSTRACT:

During this letter, the Orthogonal Matching Pursuit algorithm is introduced to model the radiation of antennas in terms of elementary sources. This algorithm, combined with the application of the Translational Addition Theorems of spherical waves, provides an correct sparse approximation of the transmitting coefficients of spherical waves by putting a reduced set of infinitesimal dipoles within the antenna location. The potency of the proposed technique is demonstrated by showing its capability to house electrically large antennas, the ease of implementation, and the computational potency. Numerical results also are presented for an array of cavity-backed patch antennas and a pyramidal horn antenna .
