Abstract: A hybrid antenna structure allows the antenna to be used internally or mostly internally in a portable radio communication device operating in the VHF range. The hybrid antenna structure includes a switching circuit that connects an RF circuit to one of several points along the length of a wrapped conductor element, depending on the selected operating frequency. An inductive matching tail element is adjustably tuned to match the selected tap point on the wrapped conductor for the selected operating frequency.
