Aim: Design of a reconfigurable microstrip planar antenna for wireless applications. Objective: To design an optically controlled microstrip planar antenna with superwideband (SWB) to multiband reconfigurable characteristics without using any biasing network. Methods: The use of photoconductive switch made of cadmium sulphide (CDS) based semiconductor is conceived to realize the optically controlled reconfigurable antenna. The operating characteristics of the proposed antenna have been changed between SWB to multiband when the CDS coating is illuminated by the light-emitting diode. Results: Under the switch-off condition, SWB of 167% (1.8-20 GHz) fractional bandwidth with higher bandwidth to dimension ratio (BDR) and a bandwidth ratio of 11.11:1 is achieved. While for the switch-on condition, triple-band (1.8-3.9 GHz, 4.3-7.3 GHz, and 8.2-15.4 GHz) operation with the resonating frequency of 3.4GHz, and 5.5GHz and, 12GHz covering the useful WiMAX, and WLAN wireless bands have been achieved with the realized peak gain of 2.34dBi, 4.18dBi, and 3.08dBi respectively. Conclusion: An optically switchable SWB to triple-band compact planar monopole antenna has been analyzed and presented based on the simulation results. This design is reasonably compact and provides better BDR than the reported antennas of its class. The proposed design is flexible enough to adjust the operating bands by varying the dimensions of the defected ground structure (DGS) and stub. This antenna with switching ability can fulfill the requirement of the antenna society for wireless applications.

Antennas with reconfigurable functionality is the mostly preferred one in the antennas field. In such scenario, a work is presented in this article proposing a frequency reconfigurable antenna with a compact PIFA kind of structure. The antenna structure has the folded radiating structure and embedded with some lumped resistance and distributed capacitance, inductance for providing the impedance matching across desired bands for wireless communication. Further, the switching elements (PIN diodes-BAR64-02V) are inserted in the gap between the long-meandered line structure for attaining the switchable characteristics among single band (0.68-0.98 GHz), dual band (0.70 – 0.96 GHz, 2.26 - 2.65 GHz), and triple band (0.69 - 0.99 GHz, 1.89 - 2.78 GHz, 3.64 – 4.1 GHz) respectively. The impedance bandwidth is considered according to S11 < -6 dB criteria for the mobile communication applications. The proposed antenna is suitable for smartphone, laptop and portable devices with GSM/PCS/WCDMA/UMTS/LTE communication applications.
