摘　　要：高集成无线收发器的集成电路封装天线(Integrated-Circuit Package Antenna,ICPA)需要同时工作在2.4GHz和5.25GHz的双频段上。它将微带贴片天线和射频收发器集成于一个独立的封装内,并使天线和收发器之间的电磁干扰最小。利用基于非均匀网格的时域有限差分方法(nonuniform Finite-Difference Time-Domain,nu-FDTD)对ICPA进行建模和仿真,并分析了设计参数对ICPA的影响以及ICPA的频率特性、远场辐射方向图和电磁场分布等。经过优化,ICPA天线可以准确地工作在双频段上。Integrated-Circuit Package Antenna（ICPA） for highly integrated wireless transceivers, is required to operate concurrently on dual-frequency at 2.4 GHz and 5.25 GHz. It combines a microstrip patch antenna with an RF transceiver into a single package, and also minimizes the electromagnetic interference between the antenna and transceiver. Using nonuniform Finite-Difference Time-Domain （nu-FDTD） algorithm to model and simulate ICPA, this paper presents analysis of the influence of design parameters, frequency speciality, far field radiation patterns and the distribution of electromagnetic field. ICPA can exactly operate on dual-frequency after optimization.
