Patent ID: 6888511

Claim:
An antenna element for use at an operating frequency and corresponding wavelength, comprising: a first sub-element having a total length of approximately one-half wavelength in a substantially rectangular shape; the first sub-element comprising first and third sides each having a length of approximately one-sixth wavelength, and second and fourth sides each having a width of approximately one-twelfth wavelength; wherein a signal is connected in series to a feed-point located at the mid-point of the first side; wherein a first gap is located at the mid-point of the third side and is a first fraction of the wavelength in length; and a second sub-element having a total length of approximately one-half wavelength in a substantially rectangular shape; the second sub-element comprising fifth and seventh sides each having a length of approximately one-sixth wavelength, and sixth and eighth sides each having a width of approximately one-twelfth wavelength; wherein a second gap of said first fraction in length is located at the mid-point of the seventh side; said first side of said first sub-element being positioned in parallel and spaced a second fraction of the wavelength apart from the fifth side of said second sub-element, such that the first and second sub-elements are magnetically coupled.
