基于耦合积分方程的数值模拟方法，研究了共面波导馈电口径耦合微带天线的特性。各种形状的激励槽，如开放的短截线，槽回路，和电容和电感耦合槽，在回波损耗和前后辐射功率比方面进行了研究。结果表明，一个中心的CPW开放短截线给出了最小的背辐射，同时允许容易匹配。槽环激励似乎是一种方便的馈电机制，也允许插入有源器件。
A numerical modeling based on the solution of coupled integral equations is used for the characterization of CPW-fed aperture-coupled microstrip antennas. Various shapes of excitation slots, such as open stubs, slot loops, and capacitively and inductively coupled slots, are investigated in terms of return loss and front-to-back radiated power ratio. It is shown that a centered CPW open stub gives a minimum of back radiation while allowing for easy matching. The slot-loop excitation seems to be a convenient feeding mechanism that also allows the insertion of active devices.
