The measured S11 shows a good agreement with the simulated one, thereby the antenna respond at five frequency bands which are (2.36-2.58 GHz), (3.07-4.01 GHz), (4.25-5.27 GHz), (5.9-6.29 GHz) and (7.01-S.l GHz) to meet requirements for WILAN (5.15-5.S75 GHz), WIMAX (3.3-3.7 GHz), LTE band (3.2-3.3 GHz) applicationsenCoplanar waveguideL-slotsMultiband antennaOther
