| Title: | Design of Low-Cost, Circularly Polarized, and Wideband U-Slot Microstrip Patch Antenna with Parasitic Elements for WiGig and WPAN Applications |
| Abstract: | In this article, a well matched U-Slot Microstrip Patch Antenna (MPA) with two paratactic elements is designed and simulated. The antenna is designed to resonate at 60 GHz (V-band) and exhibits a wideband extend from 53.3 GHz to 60.8 GHz with more than 87% total efficiency. The presence of U-slot makes a current perturbation in the antenna which contributes to generate a Circular Polarization (CP). The 3-dB Axial Ratio (AR) is extended from 56 – 57.2 GHz (~ 1.2 GHz bandwidth). The analysis and optimization processes throughout this paper are carried out using Finite Element Method (FEM) and verified with Finite Integration Technique (FIT). Good agreement between the results by the two simulators is obtained. Hence, the performance of the proposed antenna makes it a good candidate for fifth generation applications at V-band like Wireless Gigabit Alliance (WiGig) and Wireless Personal Area Network (WPAN). |

| Title: | Computational Analysis for the Combination of Inductive Coupled Wireless Coils and High Permittivity Materials to Improve B1 Field for Rhesus Monkey MRI |
| Abstract: | Magnetic resonance imaging (MRI) scanning of small animals such as non-human primates has been of interest in recent years. Imaging primates, such as rhesus monkeys, presents challenges due to the shape of their head. The shape and dimensions of the head can cause poor magnetic flux density (|B1|) strength and penetration to specific regions of interest. In this study, we focus on the design of an eight-channel, helmet-style array coil for rhesus monkey brain imaging, and performed quantitative analysis by means of electromagnetic (EM) simulations and acquiring reception sensitivity (|B1-|)-fields to demonstrate that the use of combining inductively coupled wireless coils and high permittivity materials can improve the |B1-|-field sensitivity of a tradition phase array coil. |
