摘要：
A flexible dual-band dual-polarised CPW-fed monopole antenna with discrete-frequency reconfigurability is presented here. In the proposed antenna, to achieve dual-band performance, a U-slot is incorporated within the CPW-fed monopole. The antenna is fabricated on a flexible and transparent substrate so that it can be used for conformal applications. The effect of antenna bending on its performance is discussed here. Further, the proposed antenna structure is extended to achieve discrete-frequency reconfigurability. Two p-i-n diodes are incorporated within the monopole to achieve reconfigurability of higher band. A simplified equivalent circuit of the reconfigurable antenna is also presented and validated using full wave EM simulation. To validate the proposed structure, dual-band antenna and discrete frequency reconfigurable antenna have been fabricated and tested.
