Analytical Model for Predesigning Probe‐Fed Hybrid Microstrip Antennas
International Journal of Antennas and Propagation, Volume 2018, Issue 1, 2018., 2018 Based on the equivalent resonant cavity model, an effective analysis methodology of probe‐fed hybrid microstrip antennas is carried out in this paper, resulting in a better understanding of the parameter interrelations affecting their behavior. With that, a new design criterion focused on establishing uniform radiation patterns with balanced 3 dB ...

Analysis and Design of Cavity‐Backed Probe‐Fed Hybrid Microstrip Antennas on FR4 Substrate
International Journal of Antennas and Propagation, Volume 2015, Issue 1, 2015., 2015 A novel cavity‐backed probe‐fed linearly polarized microstrip antenna based on the concept of hybrid radiators is proposed and implemented. The resulting flush‐mounted antenna exhibits symmetrical bandwidth, low cross‐polarization radiation in the H‐plane, due to its hybrid patch, and low cost, since it can be built on a FR4 laminate.

Water Resources Research, Volume 61, Issue 4, April 2025.Abstract Inland waters emit large amounts of carbon and are key players in the global carbon budget. Particularly high rates of carbon emissions have been reported in streams draining mountains, tropical regions, and peatlands. However, few studies have examined the spatial variability of CO2 concentrations and fluxes occurring within these systems ...
