Abstract
A planar antenna array and articles of manufacture using the same are disclosed. In one embodiment, close-packed antenna elements, disposed on a substrate, number N where N=3x and x is a positive integer. Each of the close-packed antenna elements includes a substantially continuous photonic transducer arranged as an outwardly expanding generally logarithmic spiral having six turns. Each of the outwardly expanding generally logarithmic spirals may be a golden spiral. As an article of manufacture, the planar antenna array may be incorporated into a chip, such as a cell phone, or an article of clothing, for example.
Claims20
A planar antenna array comprising:
- a substrate;
- and
- a plurality of close-packed antenna elements numbering N where N is selected from the group consisting of 1 and 3x, x being a positive integer, the plurality of close-packed antenna elements being disposed on the substrate, each of the plurality of close-packed antenna elements including a substantially continuous photonic transducer arranged as an outwardly expanding generally logarithmic spiral having six turns,
- wherein each of the outwardly expanding generally logarithmic spirals is described according to the following polar equation:
- r=aebθ
- with e being the base of natural logarithms, a being an arbitrary positive real constant, and b a number relative to the relationship that when θ is a turn, direction b satisfies the equation ebθright/left=φ.
An article of manufacture comprising:
- a substrate;
- a first layer superposed on the substrate and affixed thereto;
- a second layer disposed beneath the substrate and affixed thereto;
- and
- a plurality of close-packed antenna elements numbering N where N is selected from the group consisting of 1 and 3x, x being a positive integer, the plurality of close-packed antenna elements being disposed on the substrate, each of the plurality of close-packed antenna elements including a substantially continuous photonic transducer arranged as an outwardly expanding generally logarithmic spiral having six turns,
- wherein each of the outwardly expanding generally logarithmic spirals is described according to the following polar equation:
- r=aebθ
- with e being the base of natural logarithms, a being an arbitrary positive real constant, and b a number relative to the relationship that when θ is a turn, direction b satisfies the equation ebθright/left=φ.
A planar antenna array comprising:
- a substrate;
- and
- a first grouping of six close-packed antenna elements, the first grouping of close-packed antenna elements being disposed on the substrate, each of the six close-packed antenna elements including a substantially continuous photonic transducer arranged as an outwardly expanding generally logarithmic spiral having six turns;
- a second grouping of six close-packed antenna elements disposed adjacent to the first grouping, the second grouping of close-packed antenna elements being disposed on the substrate, each of the six close-packed antenna elements including a substantially continuous photonic transducer arranged as an outwardly expanding generally logarithmic spiral having six turns,
- wherein each of the outwardly expanding generally logarithmic spirals of the first and second groupings is described according to the following polar equation:
- r=aebθ
- with e being the base of natural logarithms, a being an arbitrary positive real constant, and b a number relative to the relationship that when θ is a turn, direction b satisfies the equation ebθright/left=φ.
