ICPA: Integrated-Circuit Package Antenna 高集成无线收发器的集成电路封装天线
看了一篇文章介绍这个ICPA的，原文如下：This article presents study of a dual-band integrated-circuit package antenna (ICPA), which operates concurrently on dual bands at 2.4 and 5.25 GHz. The antenna is designed and printed on the top surface of an IC package and fed by a single coaxial line, while the transceiver is implemented on the opposite side of the package, through the separation of a common ground plate. This “cavity-down” arrangement minimizes the electromagnetic interference between the antenna and transceiver, and satisfies the miniaturization of the design.
大概讲的就是：它同时接在一个2.4和5.25的双频段上，然后就是繁琐的操作，最后使天线和收发器之间的电磁干扰最小。可以分析它的远场辐射方向图和电磁场分布。

也许是的。
