摘要：
Cavity resonance antennas with dielectric superstrate are considered with different ground plane types namely, perfect electric conductor (PEC), perfect magnetic conductor (PMC), and artificial magnetic conductor (AMC). Radiation properties of these antennas are computed using transverse equivalent network (TEN) model. It is shown that the effects of angular and polarization dependency of artificial ground planes can be beneficial or detrimental to the antenna performance in directivity. © 2009 IEEE.
