Log periodic antennas are widely used in RF communication due to their broadband capabilities. One critical aspect of their performance is input impedance, which determines how efficiently the antenna transfers power from the transmission line. Understanding this parameter is essential for engineers and hobbyists working with these antennas.   Why Input Impedance Matters The input impedance o...

In radio frequency (RF) design, impedance is one of the most critical concepts. It directly affects signal transmission efficiency, matching between circuits, and system stability. Without proper impedance matching, RF systems may experience significant signal reflection, increased insertion loss, and even cause damage to components. This article provides a detailed explanation of impedance and it...
