The proposed design approach improves the circularly polarized Fabry-Perot cavity antenna (CP-FPCA) by increasing gain and sidelobe suppression (SLS) while reducing axial ratio (AR) cross-polarization levels. Conventional CP-FPC antennas have a high AR due to lack of independent control over circular polarization conditions. solution proposes double-layered partially reflecting surface (CP-PRS)...

This article proposed a simple self cascode RGC amplifier configuration to increase the gain and bandwidth. The cascode amplifier eliminates the miller capacitance between input and output and facilitates high gain, high input and output impedance with high bandwidth. However, the cascode amplifier requires relatively high supply voltage for proper operation and it decreases the output voltage ...

Purpose: Obesity is one of the most common problems in the world. Imbalance between energy consumption and expenditure is a main factor in weight disorder. Exercise helps losing weight by increasing energy expenditure and modulation of the energy intake. The present study examined protective effects of daily moderate aerobic exercise on preventing weight gain in high fat diet rats. Materia...
