Directly-coupled Microstrip Array Antennas for Wideband Application
نویسندگان
چکیده
A method for increasing the bandwidth of microstrip array antenna by adding additional resonator, which is directly – coupled to the non – radiating edges of a radiating element is narrated. The experimental result of four elements non-radiating edge directly – coupled rectangular microstrip array antenna (FNCRMAA) shows wide band with bandwidth of 15.63 %. Further extending the elements of array to eight elements non-radiating edge directly – coupled rectangular microstrip array antenna (ENCRMAA), the antenna shows improved impedance bandwidth up to 20.76 %. The design specifications, radiation patterns and gain of the proposed antennas are shown and reported.

Analysis of aperture-coupled microstrip antennas with a superstrate using space domain closed form Green's functions is presented. Integral equations are derived from applying the boundary conditions on the radiating patch, across the aperture, and on the microstrip feedline. The computation of space domain green's functions is performed using the closed-form. The solution of the integral equat...
