Abstract:
A dielectric member (12) may be thin and planar and may have first and second opposite surfaces (14,16). An electrically conductive material (18) is disposed on the first surface at one end of the first surface and an electrically conductive material (20) is disposed on the second surface at the opposite end of the second surface. The conductive materials in the first and second surfaces define a first antenna operative at a first frequency. Slots (26) are provided in the conductive material in the first surface. The slots define a second antenna operative at a second frequency greater than the first frequency.
