DUAL-BAND CIRCULARLY POLARIZED STACK-RING ANTENNA

Dual-Band Circularly Polarized Stack-Ring Antenna

A stack-ring configuration is proposed for designing a dual-band circularly polarized (CP) antenna.Each ring generates different resonant frequencies.A good CP performance at both resonant bee by bonnie and neil frequencies is achieved by adjusting the relative distance between the two rings.The two operating bands are separated with 5.11 flex shot

Corrosion inhibition study of the protective reliability of Moringa oleifera, Chrysophyllum caimito, and Camellia sinensis oil distillates on mild steel in dilute H2SO4 and HCl solutions

The protective reliability of Moringa oleifera (MO), Chrysophyllum caimito (CC), and Camellia sinensis (CS) oil distillates was examined in H2SO4 and HCl solutions.The data showed that MO and CC performed effectively in H2SO4 at 81.3% the william tuttle foundation and 93% compared to CS at 76.5%.CC and CS performed more effectively in HCl at 92.7%
