Four band patch antenna by CPW feeding for in-building mobile communication

摘要

This paper presents a design for four band patch antenna by CPW feeding for the in-building mobile communication. Especially, a parasitic element is considered for beam direction control. In order to satisfy for the mobile communication service such as LTE (890 MHz band), PCS (1.8 GHz band), W-CDMA (2.0 GHz band) and Wi-Fi (2.43 GHz band), a CPW feeding structure and a circular patch with slit for broad bandwidth are designed. The simulated results were shown a good agreement with the measured ones of a proposed antenna.
