Wideband printed monopole antenna integrated in a system in package.

A promising design of integrating a wideband printed monopole antenna in a system in package (AiSiP) for wireless local area network (WLAN) operation in the 2.4 GHz band is presented. The antenna is an inverted-F monopole antenna printed on the no-ground portion (6 × 18 mm2) of the module substrate of the AiSiP (total size 24 × 18 mm2). A parasitic shorted strip can also be added in the no-ground portion to double the operating bandwidth of the AiSiP. When mounted on the system ground plane of a wireless device, the AiSiP can provide a complete communication function, without the need of employing additional antennas in the wireless device. The proposed AiSiP is studied in the paper, and obtained results of the constructed prototype are presented. Effects of the system ground plane on the antenna performance of the AiSiP are also analyzed. © 2006 Wiley Periodicals, Inc.
