Abstract

The optimum door seal configuration to prevent radiation leakage from a microwave oven is still a manufacturing concern. Here, we propose a numerical algorithm to simulate the radiation propagation along a door seal structure using the finite‐difference time domain method, which is used for a priori shielding efficiency tests. The results agree with experimental data. The critical dimensions of the choke structure were found and high shielding is anticipated for a simpler choke structure.

## Abstract A printed meander antenna is studied using the FDTD method. The influence of a number of antenna parameters (dielectric constant, substrate thickness, and presence of ground plane) on the input impedance and radiation pattern of the antenna is examined. It is found that a 60% size reduc
