Abstract
An antenna includes one or more conductive elements for acting as radiating antenna elements, and a slow wave meander line adapted to couple electrical signals between the conductive elements, wherein the meander line has an effective electrical length which affects the electrical length and operating characteristics of the antenna. The electrical length and operating mode of the antenna may be readily controlled.
Claims4
An antenna, comprising:
- a multiplicity of conductive elements adapted for acting as radiating antenna elements including a pair of substantially identical conductive elements and a third conductive element having opposing sides;
- and
- a slow wave meander line means adapted to couple electrical signals between the conductive elements and to have an effective electrical length which affects the electrical length and operating characteristics of the antenna, the meander line means including a pair of slow wave meander lines each of which pair is adapted to serially connect a separate one of the paired conductive elements on opposing sides of the third conductive element,
- wherein the conductive elements are connected to form a loop antenna over a around plane with the pair of conductive elements forming opposite sides of the loop extending from the ground plane and the third conductive element is serially coupled with the slow wave meander lines between the pair of elements and opposite the ground plane.
