| Abstract: | A microstrip disk patch antenna with radome is simulated u sing FDTD method for dielectric effcet on radiation;perfect matched layer techni que is adopted to form absorbing boundary,contour path technique is adopted to t reat feeding port of the coaxial line and the disk patch;resonant frequency is c aculated;the numerical result of the model is identical with experimental result Furthermore,radiation pattern of the antenna is predictedThe effect of diffe rent dielectric layer and different thickness on the antenna radiation character istics(copolarization and cross-polarization)is discussed |
