Abstract :
Microstrip antennas with inhomogeneous, finite-sized substrate and ground plane are studied. Applying the finite element-boundary integral (FE-BI) method, the electric and magnetic field radiation on the dielectric boundary of the finite microstrip structures can be solved numerically, without the assumption of infinite substrate. The numerical result is compared with the one obtained by the integral equation method for the case of homogeneous substrate, and they show good consistency with each other. The effects of inhomogeneous substrate are also studied.
