Abstract
A thin film, flexible antenna that has particular application to be adhered to vehicle glass, where the antenna has a wideband antenna geometry and is operable to receive right-hand or left-hand circularly polarized signals from, for example, GPS and SDARS satellites. The antenna is a printed planar antenna formed to the substrate and includes a ground plane having a slot formed therein and a tuning sleeve having a vertical portion and a horizontal portion. The planar antenna further includes a radiating element positioned adjacent to the tuning sleeve and including a feed portion positioned within the slot, where the radiating element includes a first horizontal portion and a second horizontal portion extending from a vertical portion towards the vertical portion of the sleeve. The ground plane is operable to generate circularly polarized signals to be received by the radiating element where the sleeve provides phase tuning of the signals.
