“…As a 2D planar model is being used, it is necessary to select an antenna with a constant horizontal cross section, such as a monopole with a cylindrical parabolic reflector [14]. Due to the extremely small skin depth at 1 GHz in metals, the reflector was configured as a perfect electrical conductor surface (no width, zero skin depth).…”

Radiofrequency (RF) Through-the-Wall Mapping (TWM) employs techniques originally applied in Computerized Tomographic Imaging to map obstacles behind walls. Therefore, it can provide valuable information in military operations in urban scenarios, as well as in rescuing efforts in damaged buildings. This work proposes applying Finite Element Method (FEM) to simulate a parallel-beam geometry RF TWM setup. The use of FEM simulations allows faster evaluation of different reconstruction algorithms for several geometries and materials. Furthermore, due to time and budgetary constraints, sometimes field measurements campaigns cannot be carried out. A test floor blueprint was defined, and Filtered Backprojection Reconstruction was applied to recover the floor map. The achieved results were compared to results obtained through field measurements and available in the literature. To the best of our knowledge, this is the first use of FEM simulations in a TWM problem.

“…Currently, plasma antenna is one of the antennas that have future development in wireless communication technology especially in indoor applications. It can use as transmitter and receiver for communication purposes and at the same time, it gives light to user [4]. However, the current plasma antennas are expensive and difficult to manufacture.…”

This paper presents the development of a rectangular loop microstrip patch antenna integrated with Light Emitting Diode (LED) for Wifi application. The objective to integrate with LED is to have dual applications in a device which illumination and also wireless communication. The antenna was designed at a frequency of 2.4 GHz and Computer Simulation Technology (CST) was used to optimized the position of LED within the rectangular loop antenna. The performances of the antenna in terms of return loss, gain and radiation pattern was verified through simulation by using Microwave Studio in CST. The antenna was fabricated on FR4 substrate with permittivity, εr =4.5 and thickness,h= 1.6mm. The LED integrated within the patch was conducted parallel and was measured by Vector Network Analyser (VNA) to demonstrate the capacity and potential of the antenna. The antennas are reasonably well matched at their corresponding frequency of operations between simulation and experiment.

“…As mentioned by Alexeff et al (2006), the ionized gasses used in plasma antennas provide several other advantageous such as camouflage from waves, coupling reduction, interference reduction, noise reduction and radar cross section reduction. Due to the rigid structure of the plasma tube most published work on reconfigurable plasma antennas involved the use of a monopole-like plasma tubes (Barro et al, 2017;Dagang et al, 2016b;Halili et al, 2013;Jaafar et al, 2017;Zali et al, 2013). However, the plasma dipole antenna presented in Melazzi et al (2017) contains a horizontal plasma tube which is excited by a RF signal coupler in the middle as shown in Fig.…”

I am grateful to my PhD supervisor, Prof. Amit Mehta for all the support and guidance he has given me throughout my PhD. He has continuously funded my PhD since 2013, ensuring that I was free to concentrate on my research fully, without any financial worries. His immense support, guidance and encouragement were the reasons I managed to complete my research and thesis on time. I wish to thank my supervisor and friend, Dr. Arpan Pal, who has always been on hand to assist me during my research work in the lab. His support and assistance in completing my publications needs special mention. My parents have always been pillars of strength in my life. Their words of encouragement went a long way to ensure I remained focused during my studies overseas. My loving wife Charya, has always stood by me through thick and thin. Last year, she gifted me with a beautiful son whose innocent smile reminds me every day how lucky I am. I wish to thank Mr. Gareth Evans and Mr. David Moody from the College of Engineering for their assistance in fabricating my helmet antenna and providing other technical assistance during my research project. I also wish to thank my friend Dr. Gareth Ayres from LIS, for his assistance in the computer networking aspect of my research.
