The 2025 energy transition in eight charts: clean wins, dirty setbacks For supporters of the energy transition, 2025 had plenty to complain about: the scrapping of U.S. clean energy policies, wind ...

Abstract: This paper presents the design of a microstrip line-fed substrate-integrated waveguide (SIW) ring antenna designed to excite a sixth-order circularly polarized conical radiation pattern.

Abstract: The synthesis and optimization of the radiation pattern of a monopole circular antenna array are described. The method is fast and effective since it employs impedance and radiation pattern ...
