Abstract
A diversity handset (100) used in a personal communication system includes a flap (104), a first antenna (108) and second antenna (110). The second antenna (110) consists of two portions, the first portion being a direct feed portion (202) printed onto a substrate (206), and the second portion consisting of a parasitic radiator (116) located within the flap (104). The first and second portions (202) and (116) of the second antenna (110) are inductively coupled together between the flap (104) and the substrate (206). Diversity is maintained with the flap (104) open or closed as well as with the flap removed from the handset (100).
