Miniature antenna having a volumetric structure

A miniature antenna, comprising:

• a first radiating arm that defines a first grid dimension curve within a first plane;
• and
• a second radiating arm that defines a second grid dimension curve within a second plane;
• wherein the physical dimensions of the antenna are smaller than one-fifteenth of a free-space operating wavelength of the antenna and
• wherein the each of the first grid dimension curve and the second grid dimension curve defines a space-filling curve;
• wherein the space-filling curve comprises at least ten segments
• wherein each of the at least ten segments forms an angle with an adjacent segment of the at least ten segments and is shorter than one-tenth of the free-space operating wavelength.

A miniature antenna, comprising:

• a radiating arm that defines at least one grid dimension curve;
• the radiating arm forming a non-planar structure;
• the radiating arm including a feeding point to coupled the antenna to a transmission medium;
• wherein the physical dimensions of the antenna are smaller than one-fifteenth of a free-space operating wavelength of the antenna;and
• wherein the grid dimension curve defines a space-filling curve;
• wherein the space-filling curve comprises at least ten segments;
• wherein each of the at least ten segments forms an angle with an adjacent segment of the at least ten segments and is shorter than one-tenth the free-space operating wavelength.
