Abstract :
The effects of the finite-sized substrate and ground plane on the radiation characteristics of a microstrip antenna are studied. Applying the boundary integral method, the electric and magnetic field radiation on the dielectric boundary of the finite microstrip structures can be solved numerically, without the complicated Sommerfeld integral and the assumption of infinite substrate. Rectangular microstrip antennas with finite-sized substrate and ground plane are analyzed, and the numerical results are compared to the experimental data.
