A reconfigurable planar antenna design bandwidth operating in ultra wide band (UWB) applications with compact dimensions of (50 × 25× 1) mm3 is proposed. The switching capability is achieved by using a two PIN diodes F-shaped slot and a two narrow vertical slot. A defected ground structure is used to improve a range of frequency from 0.83 GHz to 5.24 GHz with an impedance bandwidth of 4.41 GHz. Moreover, the flow of current within the patch’s radiation is controlled via pair of PIN diodes situated at the centre with in the patch in the F-shape slot. A retractable patch antenna design is offered, and the bandwidth re-configurability is attained by manipulating the operational states of the PIN diodes. As result, we get a reconfigurable Circular Polarization (CP). Furthermore, the proposed antenna demonstrated an efficiency of 88.55% infrequencies operating at 3 dB Axial Ratio (AR) bandwidths. All achieved results shows that our antenna design is working much with 5G and UWB application.
