The effect of acquisition geometry in digital breast tomosynthesis was evaluated with studies of contrast-to-noise ratios (CNRs) and observer preference. Contrast-detail (CD) test objects in 5 cm thick phantoms with breast-like backgrounds were imaged. Twelve different angular acquisitions (average glandular dose for each ~1.1 mGy) were performed ranging from narrow angle 16° with 17 projection...
Recent wireless testbed implementations have proven that full-duplex communication is in fact possible and can outperform half-duplex systems. Many of these implementations modify existing halfduplex systems to operate in full-duplex. To realize the full potential of full-duplex, radios need to be designed with self-interference in mind. In our work, we use a novel patch antenna prototype in an...
Low-profile patch antennas have become ubiquitous in wireless terminals, especially as devices smaller and demand more functionality out of their RF subsystems. While shape size is attactive for many applications, narrow bandwidth hinders usage systems. With the rise computer-aided design, antenna design concepts been presented with enhanced capabilities. The E-shaped antenna, whose original ea...
Microstrip Patch antenna is generally used in a number of antenna systems because of their low profile, light weight, low cost, compactness etc. Patch antenna is also used with Microwave IC’s and Monolithic Microwave IC’s because of its compatibility. Reconfigurable band notches in UWB antennas are dynamic research area. The advantage of the antenna with reconfigurable band notch is to efficien...
