I want to know the answer to the following question:
Besides low gain antennas, what is also used as driven elements in complicated higher gain types of antennas?
All the background I'm provided with is that "The most widely used class of antenna, a dipole antenna consists of two symmetrical radiators such as metal rods or wires, with one side of the balanced feedline from the transmitter or receiver attached to each.". Is that enough to answer the question?
