AbstractCarbon nanotube (CNT) has emerged as potential candidate for replacement of conventional metal patch in antenna application. The principal objective of our research is to develop nanostructured flexible patch antenna array for multi- frequency operation in industrial, scientific and medical (ISM) band. Patch antenna design using CNT on flexible cotton sheets has been simulated with cotton as a substrate and CNT as conductive patch and ground plane. Due to high conformability and conductivity of CNT all antenna parameters like VSWR, return loss, gain and radiation pattern obtained using FEKO EMSS software meet design criteria. Our simulated antenna design shows a return loss less than -10 dB and VSWR less than 2 at 2.06 GHz, 2.38 GHz and 2.49 GHz. We have also simulated a versatile and conformable antenna design where the whole geometry is rolled up like patch array on cylindrical surface. Conformability to curved surfaces and integration with the structure brings about a unique antenna design. An inset fed square patch array is also proposed for RF energy harvesting operating in the 2.45 GHz ISM band that can harvest and store energy from the surrounding environment. Simulation result shows that dc voltage of 0.215 V can be achieved at -6 dbm received energy level at 2.45 GHz IEEE 802.11b band. This would correspond to potential working distance of 10m.

Abstract In 5G network, the key parts are millimeter wave band (mmWave band) involving 26 GHz & 28 GHz which aims to solve issues related to traffic using its wide bandwidth. Features of 5G such as transmitters with high directivity, wide bandwidth and base station with high density project it as a promising source of RF energy harvesting. In order to harvest RF power from the full spectrum in an efficient way, broadband antenna design is demanded. This paper focuses on designing wearable microstrip fabric antenna operating in 5G spectrum at 26 GHz & 28 GHz for RF energy harvesting. Impedance bandwidth of the antenna is about 20 GHz to 30 GHz exhibiting omnidirectional pattern of radiation with on-body gain with a peak value of 7 dB making it suitable for harvesting RF energy. On body radiation efficiency & off body radiation efficiency are obtained as 40% and 60% when operating in the frequency range of 24 GHz & 30 GHz. In mmWave band, dielectric characterization of a two line fabric substrate microstrip antenna is obtained. Fabrication of the antenna is done using polyimide copper laminates etched with ultra thin size 150 µm on a woven polyester substrate of 310 µm thickness. Improved gain and stable bandwidth are achieved from the proposed antenna design when demonstrated in human proximity providing high robustness.
