Previous University of Hawaii CubeSats constantly used new designs for each succeeding project. Having to redesign the three major subsystems (TTC, PGD, CDH) to accommodate a particular payload resulted in long development times and a steep learning curve for new members. To avoid these problems a modular subsystem design was researched and implemented. The utilization of standard connectors wi...

An effective approach to improve the detection efficiency of nanoscale light sources relies on a planar antenna configuration, which beams emitted into narrow cone. Planar antennas operate like optical Yagi-Uda antennas, where reflector and director elements are made metal films. Here we introduce investigate, both theoretically experimentally, scanning implementation antenna. Using small ensem...

5.1 INTRODUCTION MIMO wireless systems have demonstrated the potential to increase communication spectral efficiency in a rich multipath environment. From an antennas perspective, different array configurations and types of element have been proposed and analyzed for MIMO links. Nowadays in military and commercial applications there have been ever growing demands for antennas. The standard dipo...

The present work relates to the antenna design for mobile terminals. It’s about PIFA antennas (Planar InvertedFAntenna). The modification of the certain existing structures geometrical forms allowed the operation of those according to current standards. The design is performed by using the SuperNEC and HFSS simulators. The conception of four antennas: broadband, Bi-band, tri-band and quadriband...
