采用有限元法模拟了一种环绕光子晶体的微带贴片天线，求解出与理论结果有极好吻合的谐振频率，并进一步求解辐射方向图，并与常规微带贴片天线相比较证实了这种贴片天线能够抑制表面波，提高辐射增益。

[Abstract]
The finite element simulation of a photonic crystal around the microstrip patch antenna have been performed. Solving resonant frequency are excellent matched with the theoretical results, and further solving radiation patterns are compared with the conventional patch antenna , It has proved that the patch antenna can inhibit surface wave and enhance radiation gain.
