Definitions

  • the ground plane is rectangular, having a width (w) of 55mm and length (I) of 90mm and the substrate 104 is comprised of a 1.5 mm thick FR4 material with a dielectric constant of 4.4, having a width (W) of 55mm and length (L) of 105mm.
  • the dimension of the substrate is usually constrained by the size of the mobile device housing.
  • plots of measured S parameters (S11, S21 and S22), for the dual port antennas, where S11 and S22 are reflection parameters and S21 is an isolation or coupling parameter.
  • S11 and S22 are reflection parameters
  • S21 is an isolation or coupling parameter.
  • the dual-port antenna operates over multiple application bands, such as GSM/900/1800/1900, UMTS 2100 MHz bands, LTE 2.1/2.6 bands and WLAN 2.45/5 GHz bands, and the isolation between the two ports are better than - 13 dB across all bands from 500 MHz to 6 GHz.
