ABSTRACT:
A planar dipole antenna is arranged on a non-conductive substrate having an exposed, planar surface. The antenna includes a first quarter wavelength element having a first end and an opposite second end and a second quarter wavelength element having a third end and an opposite fourth end. The first, second, third and fourth ends, respectively, are arranged on a common straight line with the second and third ends adjacent to each other. A third quarter wavelength element, having a fifth end and an opposite sixth end, is arranged adjacent to the first element with its fifth end adjacent to the first end of the first element and its sixth end both adjacent to and physically connected with the third end of the second element. A signal source or sink is coupled to the first end of the first element and the fifth end of the third element, respectively, for providing electrical energy to, and/or receiving electrical energy from the antenna.
