Ultra-Compacted Antenna-based Capsule Endoscope in the ISM Band Marwah Hassooni, Jabir Aziz, Ashwaq Hameed, Hadeel Hussein Advanced Electromagnetics, 2025 This article presents a proposal for the miniature implantable antenna of a microstrip patch that covers ISM bands (2400–2483.5 MHz) for deep-tissue implantation with a volume of just 0.3 mm³. The proposed antenna is the smallest and lightest antenna manufactured for wireless capsule endoscopy. The antenna can be integrated with an imaging sensor, electronic components, and a battery. The proposed Microstrip Patch Antenna MPA shows a 483 MHz wider bandwidth at 2483.5 MHz; Beef muscles were used to validate the antenna's performance experimentally. The safety issues are assessed to examine the performance of the proposed antenna incorporated in an endoscopy capsule device by considering the specific absorption rate (SAR).

Design and implementation of compact dual-mode BPF using moore fractal geometry Abdullah A. Marzah, Jabir S. Aziz Proceedings of the World Conference on Smart Trends in Systems Security and Sustainability Ws4 2020, 2020 This work introduces the design, simulation, and implementation of a high-performance bandpass filter (BPF) for wireless applications. Size reduction becomes an important condition in filter design with minimum reflection coefficient, low insertion loss, out of band rejection, linear phase and flat group delay. Also, these filters needed to be easily integrated with transceivers and should be manufactured at a low cost. In this design, the microstrip structure was used with electrically coupled open loop resonators BPF based on Moore fractal geometry technique. FR-4 substrate with dielectric constant 4.3, and thickness 1.6 mm has been used. The proposed filter that centered at the 5.8 GHz frequency is simulated and evaluated using CST microwave studio package. The proposed filter structure is then fabricated to experimentally validate the simulated parameters, insertion loss and return loss in the desired bands of interest and out of band rejection level. Results of simulation and implementation show that the proposed filter possesses high performances and minimum size (with dimensions of 8.83 mm × 6 mm) enabling their use in a variety of wireless communication applications.
Bandwidth and Input Reflection Coefficient Enhancement for Printed Elliptical Monopole Antenna Mohammed Z. Hadi, Jabir S. Aziz Nicst 2019 1st Al Noor International Conference for Science and Technology, 2019 In the current era, the rapid growth of wireless communications is leading to mass spectrum, which made the need to the monitoring systems that need unique antennas with ultra-wide bandwidth and reduced size in order to monitor and control the spectrum. Planar monopole antenna PMA is the preferred solution to design a reduced size and ultra-wide bandwidth antenna. This paper presents the design and implementation of new printed elliptical monopole antenna PEMA operating in the frequency range 1–18 GHz with very low input reflection coefficient (−15 dB on average) for EM radiation monitoring applications. The antenna bandwidth was further increased with a modified elliptical ground. Design and parameters optimization of the modified elliptical ground fulfill the bandwidth and input reflection coefficient requirements. Simulation results are introduced and validated with the measured ones. The antenna was printed on an FR4 substrate of 1.6 mm thickness and the resultant size of the proposed antenna is 75 mm × 65 mm.
A miniaturized fractal based hexagonal open-loop resonator BPF for WiMAX applications Abdullah A. Marzah, Jabir S. Aziz ACM International Conference Proceeding Series, 2019 RF/Microwave filters represent an important component in most modern wireless communication systems since they reject unwanted signals (noise) and pass the required frequencies. Emerging new generations and development of communication systems need for good performance and miniaturized Band Pass Filters (BPFs). Minkowski fractals used as a miniaturization technique has been applied to slotted hexagonal loop resonator for designing BPF operate at a 3.5GHz resonance frequency which is suitable for WiMAX applications. The proposed filter has been designed using FR-4 substrate with dielectric constant 4.3 and thickness 1.6mm. More than one structure has been simulated. The overall dimensions of the second iteration Minkowski fractal proposed BPF are 7.07mm x 9.88mm which is demonstrates 80.46% reduction in size as compared with conventional closed hexagonal loop resonator BPF. CST microwave studio suite software package has been used in the simulation.

A hybrid propagation coverage prediction model for mountainous areas Ahmad S. Abdulrasool, Jabir S. Aziz, Sadiq J. Abou-Loukh International Conference on Advances in Sustainable Engineering and Applications Icasea 2018 Proceedings, 2018 The design and optimization of cellular communication networks in mountainous and hilly areas requires extra caution. The main problems are the shadowing resulted from obstruction and overshooting resulted from excessive elevation of base station or mobile. The empirical propagation models are used for the design and optimization of cellular networks, but such models do not consider the effect of shadowing or elevation fluctuation as they do not consider the terrain details strictly. The site-specific models are accurate, but the high complexity and time requirement limit their use for such purposes. This paper proposes a simplified propagation model with good accuracy that can be used for coverage prediction in mountainous nature areas. Also, the proposed model uses layering mechanism similar to Geographic Information System (GIS) in topographic layers to reduce the computation overhead and time by processing each layer alone. The validation of the proposed model will be done by comparing the results with field measurements. A coverage optimization case study using the proposed model will be done as well.
