PURPOSE: A communication module of SIP(System In Package) structure mounted with an antenna for blocking an electromagnetic wave is provided to minimize the communication module by forming an antenna on a low temperature heating. CONSTITUTION: A low temperature cofired ceramic cap(130) is formed on a substrate(100). The low temperature cofired ceramic cap blocks the electronic wave by covering the communication devices. An antenna(140) is formed on the low temperature cofired ceramic cap. The low temperature cofired ceramic cap comprises laminated first and second dielectrics. A ground is formed between the first and second dielectrics. |
