Wearable slot antenna at 2.45 GHz for off-body radiation: analysis of efficiency, frequency shift and body absorption
Marta Fernandez, Hugo G. Espinosa, David V. Thiel +1
The interaction of body worn antennas with the human body causes a significant decrease in the antenna efficiency and a shift in the resonant frequency. A resonant slot in a small…
Maximum-Entropy-Rate Selection of Features for Classifying Changes in Knee and Ankle Dynamics During Running
Garry A. Einicke, Haider A. Sabti, David V. Thiel +1
This paper investigates deteriorations in knee and ankle dynamics during running. Changes in lower limb accelerations are analyzed by a wearable musculo-skeletal monitoring system.…
Fundamental limitations for antenna radiation efficiency
Morteza Shahpari, David V. Thiel
Small volume, finite conductivity and high frequencies are major imperatives in the design of communications infrastructure. The radiation efficiency impacts on the optimal g…
The impact of reduced conductivity on the performance of wire antennas
Morteza Shahpari, David V. Thiel
Low cost methods of antenna production primarily aim to reduce the cost of metalization. This might lead to a reduction in conductivity. A systematic study on the impact of conduct…
Point Contacts in Modeling Conducting 2D Planar Structures
David V. Thiel, Morteza Shahpari, Jan Hettenhausen +1
Use of an optimization algorithm to improve performance of antennas and electromagnetic structures usually ends up in planar unusual shapes. Using rectangular conducting elements t…
Polarizablity of 2D and 3D conducting objects using method of moments
Morteza Shahpari, David V. Thiel, Andrew Lewis
Fundamental antenna limits of the gain-bandwidth product are derived from polarizability calculations. This electrostatic technique has significant value in many antenna evaluation…
An investigation into the Gustafsson limit for small planar antennas using optimisation
Morteza Shahpari, David V. Thiel, Andrew Lewis
The fundamental limit for small antennas provides a guide to the effectiveness of designs. Gustafsson et al, Yaghjian et al, and Mohammadpour-Aghdam et al independently deduced a v…
