Patent attributes
A microstrip antenna includes a substrate having a first surface and an opposing second surface, a ground plane disposed at the first surface of the dielectric layer, and a conductive layer disposed at the second surface of the substrate. The conductive layer includes a continuous conductive trace comprising a plurality of linear segments arranged in a near-closed polygonal chain. The near-closed polygonal chain can define a truncated square spiral shape. Alternatively, the near-closed polygonal chain can define one of a near-closed pentagonal shape, a near-closed hexagonal shape, a near-closed heptagonal shape, and a near-closed octagonal shape. The antenna can be operated to communicate electromagnetic signaling responsive to current signaling provided by the transceiver circuitry, either by driving electrical current signaling at the microstrip antenna to generate the electromagnetic signaling or by receiving the electromagnetic signaling at the microstrip antenna and converting it to electrical current signaling.
