Two-Port Antenna With High Isolation for DTV/GSM/Umts Indoor Applications

Abstract

Abstract-A two-port antenna with high isolation for digital television system (DTV), global system for mobile communication (GSM), and universal mobile telecommunications system (UMTS) indoor applications is presented. The antenna consists of a disk loaded sleeve monopole antenna and an inverted-L plate antenna, which are combined into one radiation structure. In addition, by using a choke tube and C-shaped slot inserted into the plate, the isolation between the two ports is improved. A prototype is constructed and tested. The simulated and measured results are given.
