Abstract
In order to simulate the influence of the thermal effects of a patch antenna on its electromagnetic radiation performance, the discontinuous Galerkin time domain (DGTD) method and finite element time domain (FETD) method are employed to implement electromagnetic-thermal co-simulation. The Maxwell equation is solved by DGTD method, while the heat conduction equation is solved by FETD method. The electromagnetic and thermal simulation are linked by loss power of material and temperature dependent conductivity. Numerical results show that the radiation pattern will change if we consider the thermal effects of the patch antenna.
