Differentially fed active antennas
… set out with a review of the state-of-the-art in active integrated antennas. Following that, the ground plane influence on antenna radiation pattern was explored and novel techniques to compensate the effects were presented. It was observed that the current flow in a coaxial cable also affects …

Development of Integrated "Chip-Scale" Active Antennas for Wireless Applications
… data networks (WLANs). Integrated microstrip antennas coupled directly to the RF electronics, offer potential advantages of low cost, reduced parasitics, simplified assembly and design flexibility compared to systems based on discrete antennas. However, the size of such antennas is governed by …

Architecture and Design Considerations of Active Antennas on Space Based Platforms
The design of antennas for space-based applications requires that particular attention be paid to various requirements imposed on the design by the space environment. Additional requirements are driven by the platform on which the antenna will be hosted as well as by the intended use of the …

Investigation of plasma potential enhancement in the scrape-off layer of ion cyclotron range of frequencies heated discharges on Alcator C-Mod
… directly magnetically map and do not map to the active antennas experience plasma potential enhancement. The "mapped" results are consistent with the slow wave rectification mechanism where the plasma potential enhancement is a result of rectification of the slow ICRF wave electric field launched …

Time-Variant Components to Improve Bandwidth and Noise Performance of Antennas
… Thus, the design of low-noise devices (such as antennas, amplifiers, and filters) is essential to increase the communication range. Also, it is well known that the noise performance of a receiving radio is primarily determined by the frontend including the antenna, filter, and a low-noise …
