 The proposed design of this fanstub slot patch antenna is optimized to provide optimal performance for both citizens broadband radio service, CBRS, and 5.5 GHz wireless local area network, WLN, BANDS. The transition from the tedious configuration of slotted patch antennas in fanstub shape is evaluated, with multiple simulations testing the impact of stub with W, stub length L, and its orientation on the multi-band nature of the patch. The optimization of the basic fanstub structure on return loss S11, voltage standing wave ratio, VSWR, and the operating band at the desired frequency is performed to accommodate the federal and non-federal use of the band. Simulation results show that the designed antenna is technically suitable to cover 4G LTE and CBRS, LT43 and LT48 band, as well as 5.5 GHz WLN band of operation.
