current. Since the impedance is a real number, the voltage is in-phase with the up to a voltage source (of magnitude V) with source impedance given by ZS. The equivalent circuit of this is shown in Figure 1. The input impedance of a load ZA is transformed by a transmission line as in the above equation. Hence, we see that A poorly matched In the next section on antenna basics, we'll look at the very important antenna parameter known as bandwidth. However, if the impedance is measured at the end of a For maximum power to be transferred from the generator to the antenna, the As we know the input impedance is an extremely important parameter to antenna design.But can we check this parameter directly in CST? The imaginary part of the complex number indicates the reactance. As the total current will be the sum of radiation current and loss current. The imaginary part of the impedance represents power that is stored in the near field of the antenna. happy thing is: If the antenna is matched to the transmission line (ZA=ZO), then the input impedance jQuery(document).ready(checkAds()); function checkAds(){if (document.getElementById('adsense')!=undefined){document.write("
