SIP(SYSTEM-IN-PACKAGE) EMBEDDING FOLDED TYPE SP(SHORTED-PATCH) ANTENNA AND METHOD FOR DESIGNING SIP THEREOF

摘要

An SiP(System-in-Package) with a folded type SP(Shorted-Patch) antenna and a method for designing the same are provided to reduce cost and to improve performance by using a microstrip line as a feed unit of the folded type SP antenna. An SiP(400) with a folded type SP antenna(408) includes first and third layers(402,406). A second layer(404) is arranged between the first and third layers. A ground plane(410) is formed on the first and third layers. A patch(412) is formed on the second layer. A short-circuit between the ground plane and the patch is formed by a through-hole via or a via wall. The SiP further includes a feed unit(414) to feed current to the patch. The feed unit has a micro-strip line.
