Abstract
A diversity antenna system that operates within a low frequency band ranging from 700 Megahertz is disclosed. A plurality of antennas are folded onto a single printed circuit in a meander pattern configuration. Each antenna has an independent feed port and ground pin. The plurality of antennas are configured within a compact mobile phone space to produce a high isolation and low correlation at resonating frequencies within the 700 Megahertz frequency band.
