High efficiency antenna

摘要

Antenna designs are disclosed that exhibit both high bandwidth and efficiency. A first aspect of the invention concerns the form factor of the antenna; a second aspect of the invention concerns the ease with which the antenna is manufactured; and a third aspect concerns the superior performance exhibits by the antenna across a large bandwidth.

主权项

1. An antenna, comprising:
two conductive metal antenna elements, each element comprising one-half of a dipole antenna; each antenna element being a mirror image of the other and formed on a rigid substrate in spaced relation to define a gap there between that provides stable antenna impedance and reactance, a portion of each antenna element at said gap defining a connection pad for connecting a coaxial cable thereto, each antenna element having a profile defining a curved, semi-circular inner edge and an arc-shaped outer edge that define the connection pad of the antenna element at the gap; wherein each antenna element extends from a narrow portion thereof to a point where the edges diverge and define a wide, curved upper element portion, the outer edge of each antenna element further defining a semi-circular projection that bulges from an upper portion of the outer antenna element edge.
