摘要

An innovative and simple method for attaining broadband frequency reconfigurable antennastructure is presented using low-cost materials and a compact design. The frequency reconfigurabilityis attained by the “OFF” and “ON” mechanisms of three PIN diodes. Many performanceobservations are carried out such as reflectance coefficient, bandwidth (BW),resonance frequency, electric field, feed position variation, and gain among different configurations.The suitability of the presented work for the different applications lies in the X frequencyband. The resonating frequency for all switch OFF modes is achieved at 13.2 GHz andone switch ON mode at 10.7 GHz. The proposed design yields the frequency tunability behaviorover the broadband of 2.5 GHz. The design yields the directivity of 5.58 dB, the minimumreflectance coefficient of ?17.27 dB, and a total gain of 3.87 dB. This design offers an electricfield of 46 558 v/m, a BW of 340 MHz, and a normalized directivity of 87° using low-cost substrates.The results of the presented design were also fabricated and related to simulatedresults. Performance observation of the proposed work with previously published researchwork is also included. The presented design provides the solution of the low-cost, compact,reconfigurable antennas, which can be used for next-generation communication systems.
