Multidisciplinary Senior Design Project

Textile Antennas & Phased Antenna Arrays

There will be a table showcasing the graduate research performed by Dylan Bennish & Christopher Bonin, under our graduate advisor Dr. Jayanti Venkataraman. There will be a slideshow presentation and poster showcasing each of our research, along with the display of physical prototypes. The tentative plan is to have a vector network analyzer (VNA) showcasing the performance of our antenna prototypes. Dylan's research is on multi-layer textile antennas for tracking and monitoring blood glucose levels for diabetic patients. Chris' research is on the integration of electronic phase shifters with linear antenna arrays to achieve continuous scanning for a variety of applications.

The goal of Dylan's research is to use antennas to replace the need for invasive blood glucose monitoring techniques, such as the modern Dexcom device.

Beveled_Monopole_RP_S11

Initial two layer antenna with radiated energy into and out of the body.

4_layer_Antenna_Design

Revised four layer antenna with radiated energy directed into the body to take return loss measurements to obtain resonance frequency.

On_body_measurements_using_VNA

The antenna is placed upon the body and the return loss is measured using a vector network analyzer to obtain the resonance frequency.

Glucose_levels_compared_with_antenna_response

A change in glucose levels shows a respective change in the antenna's resonance frequency.

Series_Fed_Uniform_Antenna_Array

Series-fed antenna array designed for 9GHz operations.

Radiation_Pattern_of_Array

Radiation pattern of antenna array. The objective of Chris' research is to integrate integrate electronic phase shifters to achieve beam-steering.

Electronic_Phase_Shifter_utilized_for_array

The electronic phase shifter utilized is Qorvo's analog phase shifter CMD297P34. This phase shifter only requires a voltage source to achieve its phase difference.
