Linear microstrip array with serial excitation: Numerical modeling and experiment

In the work the two designs of linear microstrip antennas arrays with serial feeding system are described. The arrays are intendment for plane one-dimensional scanning antenna array. The antenna arrays are multilayer: down dielectric layer is microstrip antenna substrate, top dielectric layer is designed for antenna protection. The antenna array feeding system is serial type and have parasitic elements for matching in X-band. The matching bandwidth no less than 5-10% from central frequency of work band. The paper deal with results of numerical modeling of linear microstrip arrays and results of experimental research.
