loading inserts a coil at the middle of the rod length to distort the current distribution alongthe conductor. To add a capacitive load, a circular conductive plate is attached onto the topof the monopole. These coil and plate electrically lengthen/ the antenna, and therefore, a

physically shorter structure can be used to obtain the required radiation properties.
