Line and antenna

Nettet2. aug. 2024 · The width of a line affects both its capacitance and inductance. The length of a line affects only its delay, and its attenuation. If a transmitter and an antenna are the same impedance, and connected by a line of that impedance, then the length of the line connecting them is irrelevant (except for ohmic losses causing attenuation). Nettet1. mai 2024 · For a good antenna system, it is imperative to ensure that the transmission line is in no way a part of the antenna radiating system. It should be isolated from any possibility of playing a role in signal radiation. This is why a balanced antenna system based on a Dipole type configuration is by far superior in comparison to an EFHW …

NettetSince antennas are high-frequency devices (in the sense that their size is on the order of a half wavlength or more), transmission line effects are often VERY important. That is, if the length L of the transmission line significantly alters Zin, then the current into the antenna from the source will be very small.
