miniaturized quadrature coupler using low cost instant inkjet Printing Technology
Microwave and Optical Technology Letters, 2017Co-Authors: S A Abale, Sharul Kamal Abdul RahimAbstract:This article presents the design and implementation of a Miniaturized 3 dB hybrid coupler with low-cost instant inkjet Printing Technology. The coupler has a promising potential advantage in applications in antenna beam forming network and feeding networks for phased antenna array. Explicit design equations were derived and used in the design of the coupler. To validate the design procedure, a prototype of the 3-dB coupler was implemented using the low-cost instant inkjet silver-nano Printing Technology. The responses of the hybrid show that the return loss and isolation are both below −20 dB at the designed frequency. The size reduction of this coupler is 73.7%. However, there is little drop in the bandwidth from that of the conventional coupler. This bandwidth reduction is a payback for the significant size reduction.

Implimentation of 4×4 butler matrix using silver-nono instant inkjet Printing Technology
2017 IEEE 3rd International Conference on Electro-Technology for National Development (NIGERCON), 2017Co-Authors: Suleiman Aliyubabale, S. H. Lawan, Sharul Kamal Abdul Rahim, Stella IfeomaorakwueAbstract:Butler Matrix (BM) beamforming network using silver-nano Printing Technology is presented in this paper. It employed a 3dB coupler, phase shifters and a crossover. Closed form design equations are derived based transmission line theory. To validate the design procedure, the device is fabricated using an instant inkjet Printing Technology. The results obtained shows good return losses better than-19dB at all the input ports with an average deviation in the transmission coefficients less than 1dB. However, the device exhibited a phase imbalance of less than 0.9° at the center frequency.

DNA biosensing with 3D Printing Technology.
The Analyst, 2017Co-Authors: Adeline Huiling Loo, Chun Kiang Chua, Martin PumeraAbstract:3D Printing, an upcoming Technology, has vast potential to transform conventional fabrication processes due to the numerous improvements it can offer to the current methods. To date, the employment of 3D Printing Technology has been examined for applications in the fields of engineering, manufacturing and biological sciences. In this study, we examined the potential of adopting 3D Printing Technology for a novel application, electrochemical DNA biosensing. Metal 3D Printing was utilized to construct helical-shaped stainless steel electrodes which functioned as a transducing platform for the detection of DNA hybridization. The ability of electroactive methylene blue to intercalate into the double helix structure of double-stranded DNA was then exploited to monitor the DNA hybridization process, with its inherent reduction peak serving as an analytical signal. The designed biosensing approach was found to demonstrate superior selectivity against a non-complementary DNA target, with a detection range of 1–1000 nM.
