Vehicle Communication: Low-Profile Dual-Frequency Antenna
The Problem:
To prevent traffic accidents, U.S Department of Transportation plans to enforce future automobiles to incorporate dedicated short-range communication devices (DSRC), which accommodates vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. To date, there has not been an antenna small or efficient enough to transmit...

Reducing the Extra Noise: Patch Antennas with Ferrite Cores
The Problem:
Microstrip patch antennas are widely used in advanced wireless communication systems, however, they suffer from excess harmonic radiation. During the transmission of information between antennas (such as a phone call), noise from other parts of the system is captured. This “noise” then affects the quality of the information...

Method for Radio Direction Finding and Channel Sounding
The Problem:
Radio direction finding is a technique used to determine the angle of arrival (AoA) of an incoming radio-frequency wave signal to understand the propagation environment in urban and suburban settings. The AoA estimation is widely utilized in emergency services, geolocation of cell phones, amateur HAM radios, and will serve in connecting...

Spiral Antenna with Perturbation Elements
The Problem:
Current antennas on the market allow for either circular polarization or wide bandwidth range, but not both. Also, if the technologies available today were combined the resulting antenna would be too large for its intended applications in auto, aviation and telecommunications. CubeSat antenna development specifically faces several challenges,...
