The design consists of two symmetric inverted-F antennas separated by 0.12 ?0. The high isolation is achieved by adding a meander line immersed in inverted T-slot shaped in the ground plane which is a vital element for the least three bands. Moreover, two V-shaped slits were etched on the two 50 ? transmission lines to modify the impedance matching. The S 11 < -15db to ensure the high isolation of the proposed design that covers multi-range bandwidth. The proposed design was modified by shifting the vias locations, chamfering the edges of the feeding lines and extending the length of the inverted-F antennas to cover the lower band of WIFI. The proposed design dimension is 52�77.5 mm 2 . � 2018 IEEE.Englishhigh isolationInverted F-antennaMIMO antennaquad bandUSB dongleWIFIWIMAXAntenna groundsMobile antennasWi-FiWimaxWireless local area networks (WLAN)High isolationInverted F-antennasMIMO antennaQuad bandsUSB dongleMicrowave antennasConference Paperhttps://doi.org/10.1109/APUSNCURSINRSM.2018.8608899PubMed ID :
