View Patent ↗A multi-frequency wireless access device including a first waveguide having a pair of parallel metal plates with open sides and a slot in one of the metal plates, the slot permitting radiation to leak out, the leaked radiation illuminating a range of angles depending on frequency.
1. A multi-frequency wireless access device comprising:
a plurality of leaky waveguides, each of the leaky waveguides comprising a pair of parallel metal plates with open sides and a slot in one of the metal plates, the slot permitting radiation to leak out, the leaked radiation illuminating a range of angles depending on frequency, and wherein each of the leaky waveguides is oriented at a different angle with respect to the other leaky waveguides of said plurality of leaky waveguides.
2. The multi-frequency wireless access device of claim 1 wherein the leaky waveguides are fused into a regular polygon structure.
3. The multi-frequency wireless access device of claim 2 wherein a total number of leaky waveguides is less than ten.
4. The multi-frequency wireless access device of claim 2 wherein the fused waveguides combined with exploitation of specular reflected paths yield a rich set of frequency-angle capabilities while retaining implementation simplicity.
