Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a single radio frequency (RF) feed and a folded monopole element coupled to the single RF feed. The folded monopole element is an integrated WAN/GNSS antenna that receives electromagnetic energy in a first frequency band and receives electromagnetic energy in a second frequency band. The first frequency band is a wireless area network (WAN) frequency band and the second frequency band is a global navigation satellite system (GNSS) frequency band. The apparatus further includes an impedance matching circuit coupled to the single RF feed. The impedance matching circuit includes a diplexer to extract out GNSS frequency signals received by the folded monopole element from WAN signals received by the folded monopole element.
