The first conductor pattern, the second conductor pattern, and the third conductor pattern are respectively isolated on the first side, the second side, and the third side, and are independently positioned.

A radio frequency identification (RFID) enabled mirror includes a mirror comprising a reflective layer. The reflective layer comprises at least one layer of a metallic material. At least one portion of the reflective layer is removed to form a booster antenna from a remaining portion of the reflective layer. A dielectric coating is applied to the mirror where the reflective layer was removed. The RFID-enabled mirror further includes an RFID chip coupled to the booster antenna.

A method and apparatus for impedance matching for an antenna aperture are described. In one embodiment, the antenna comprises an antenna aperture having at least one array of antenna elements operable to radiate radio frequency (RF) energy and an integrated composite stack structure coupled to the antenna aperture. The integrated composite stack structure includes a wide angle impedance matching network to provide impedance matching between the antenna aperture and free space and also puts dipole loading on antenna elements.

Techniques and mechanisms to transmit signals with an antenna array. In an embodiment, a first signal is received at a first input of the first antenna while a second signal is received at a second input of the second antenna. A difference in phase differentials—the phase differentials each between the first signal and the second signal—results from propagation of the first signal and the second signal in the antenna array and from a difference between respective configurations of the first antenna and the second antenna. Each of the first antenna and the second antenna has respective emitters distributed along the length thereof. In another embodiment, the first antenna and the second antenna have different respective dielectric structures or different respective distributions of emitters.
