Design and analysis of slotted antenna array for 5G application

A compact 1 × 4 slotted antenna array for 5G application is designed and analyzed. The designed antenna consist of a power divider network and a rectangular shaped slot etched at bottom in ground plane. The dimension of this antenna is 29.9 × 28.7 × 0.13 mm
³
. The substrate is used as Rogers RO3003 having dielectric constant of 3 and loss tangent (tan δ) of 0.013. Performance analysis of the antenna array is carried out by changing the length of the slots. This shows the improvement in values of return loss, bandwidth and gain. The maximum impedance bandwidth is obtained as 1270 MHz at slot length of 4.01 mm. The directivity and gain of the antenna is improved with the changed length of slots at a constant width 0.45 mm. This antenna array can be used for 5G application.
