Abstract Influence of electrical large platform on antennas can not be ignored when designing effective electric system. In this article, a hybrid technique, which combines two current-based method: Method of Moment(MoM) and Physical Optics(PO), is preferred to take the platform effects into account through PO current when solving the antenna by MoM , and the NURBUS-PO is applied further to reduce the complexity of modeling and computation, thereby making it impossible to solve the antenna-platform system through MoM. The analyzing results of MoM and hybrid technique show that the effects of platform is obvious, while the hybrid technique is accurate enough and spare great computational time and storage, providing a good access to solve the EM characters of antennas on electrical large carrier.
