Abstract

This work first moment focuses on the concept of reconfigurable wide bandwidth using novel extraction technique of slotted monopole antenna with RF carbon nanotube (CNT) network. The entire approach is folded into four different designs. The first design proposes a monopole antenna where asymmetric flower type corners and mushroom shape encloses by T-slot is cut on the patch. This new shaped antenna covers wide impedance bandwidth of about 14.5 GHz within range from 21.5 to 36 GHz. The proposed antenna observed that lower bands are excited with new resonating modes by inserting T-slot upon mushroom shape while higher bands are effected due to asymmetric flower type corners on the patch. A wide range of gain from 16.3 to 20.5 dB with maximum axial ratio bandwidth of 2.8% is also succeed. Measured and simulation results for proposed antenna shows good agreement with each other. In second design, a novel extraction technique is used for equivalent model of slotted monopole antenna which shows promising agreement with the original geometry. Thirdly, introduces RF CNT equivalent model which demonstrates its ability to resonant at wideband within range of 12.4–25.1 GHz with 68% of fractional impedance bandwidth. Finally, RF equivalent model of slotted monopole antenna is integrated with CNT for the proper operation. The fabrication of integration network scenario proves notability of reconfiguration in aspect of wide bandwidth with the compactness. A frequency switchable notability dominant some excited additional resonant modes using proper impedance matching between proposed antenna and RF CNT. This proposed work is fascinating to our integration network which fully covered K-band and almost for Ka-band application.
