Ultra-small planar antennas

An antenna comprising:

• a circuit board comprising a first major surface and a second major surface opposite the first major surface;
• the circuit board defining a connector aperture for a signal feed line, the connector aperture extending between the first major surface and the second major surface, the connector aperture being offset from a center of the circuit board towards a first near edge of the circuit board;
• a patch element formed on the first major surface and extending at least between the connector aperture and the first near edge;
• at least one ground connector element formed on the second major surface in register with the patch element;
• at least one via connecting the patch element to the at least one ground connector element;
• a coaxial connector comprising a signal feed line and a connector collar, the connector collar cofacing the second major surface and being fixed to the at least one ground connector element and the signal feed line extending through the connector aperture and being electrically connected to a connector pad on the first major surface;
• a radiating element formed on the first major surface and comprising a meander line trace having a meander line portion connected at a first positon to the connector pad, the radiating element extending laterally with respect to the coaxial connector away from the near edge of the circuit board so that the meander line trace may radiate in free space.
