A wideband dual feed antenna is designed and manufactured for multi-input, multi-output (MIMO) application. The antenna is optimized to match the ports to 50 ohm, and adjust the isolation between the ports for more than 15 dB in 2-6 GHz frequency band. The disk is fed using the microstrip transmission lines with 90° angular spacing to reduce the cross polarization and hence coupling between the ports. Due to the disk radiator, the antenna can be utilized as a two ports omnidirectional antenna. The antenna is measured for S-parameters and gain that comply well with the simulations. Antenna measured gain varies between 2.3 dBi and 6.3 dBi for 2-6 GHz. The antenna can be employed as a two port compact antenna, for multiband communication in 2-6 GHz and for WLAN applications.
