LP/CP Re-configurable Antenna for 5G Applications

this paper, presents a polarization re-configurable antenna for 5G applications operating at 3. 5GHz for n78 band. A micro-strip fed rectangular patch antenna is used in this design. A slant rectangular slot is made into the patch to divide it into two parts. One part is connected to the strip feed and another part with gap made due to slot. The non fed part of the patch is connected to an E-shaped stub in a slant way similar to the slot. A PIN diode is placed into the slot to make connection in between the two parts. The PIN diode switching condition helped in shifting polarization from linear to circular vice versa, making the antenna suitable for 5G applications.
