Novel Biconical Antenna Configuration with Directive Radiation [PDF]
Journal of Electromagnetic Waves and Applications, 2009 In this paper a novel biconical antenna geometry has been proposed that has directive radiation pattern, higher gain and enhanced front to back ratio. Wide band performance is another characteristic of this new antenna. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down.

On the Design of Conical Antennas for Broadband Impedance Matching Performance
International Journal of Antennas and Propagation, 2017 In the scope of broadband radiators, the biconical antenna, or its monopole conical counterpart, is long known to be a proper choice. One common form of such radiator, the spherically capped conical antenna (SCCA), has closed-form solution to its input ...

Radiation‐Resistant Kr‐Selective MOF With Record Kr/Xe Selectivity at Elevated Pressure
Advanced Science, Volume 13, Issue 41, 22 July 2026.ABSTRACT The separation of Kr/Xe from spent nuclear fuel off‐gas is critical, yet most current adsorbents exhibit Xe‐Kr co‐adsorption under elevated pressures, posing challenges for industrial pressure swing adsorption processes. Herein, we present and evaluate a metal‐organic framework, CALF‐20M‐w, engineered for molecular sieving separation of Kr/Xe ...

Analysis of Simulated and Measured Indoor Channels for mm-Wave Beamforming Applications
International Journal of Antennas and Propagation, 2018 Ray tracing- (RT-) assisted beamforming, where beams are directly steered to dominant paths tracked by ray tracing simulations, is a promising beamforming strategy, since it avoids the time-consuming exhaustive beam searching adopted in conventional beam

Low‐Temperature Hydrothermal Synthesis of PbUO4
Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.A low‐temperature hydrothermal route for synthesizing phase‑pure orthorhombic PbUO4 is demonstrated using metaschoepite and lead nitrate at 150°C–240°C. Systematic variation of pH, temperature, and reaction duration reveals that PbUO4 formation is strongly controlled by solution chemistry, with hydrated Pb‐U phases forming at lower pH and direct ...
