The length of the antenna is theoretically 1/4 wavelengths or 1/2 wavelengths, which maximizes efficiency. This length isDegree refers to the actual length of the antenna, and for an antenna, another parameter is the electrical length, which is not only related to the actual length of the antenna, but also to the frequency of the radiated signal of the antenna, the electrical length h of the antennaeThe calculation formula of (a) is as follows:
