Abstract
An antenna for receiving and/or transmitting circularly and/or linearly polarized RF signals includes a radiation element, a ground plane, a dielectric substrate, and a feed line. The radiation element is disposed on a pane of glass. The radiation element defines a slot having a first leg and a second leg forming the shape of a cross for generating the circular and/or linear polarization. The cross-shaped slot includes a center point. The ground plane is disposed substantially parallel to and spaced from the radiation element. The dielectric substrate is sandwiched between the radiation element and the ground plane. The feed line extends within the dielectric substrate and is electromagnetically coupled with the radiation element and the ground plane. The feed line terminates at a distal end short of the center point of the slot. That is, the feed line does not cross the center point. The antenna is compact in size and generally conformal to the pane of glass.
