Abstract
A dual-band patch antenna is described. The antenna includes a ground plane. The antenna also includes an inner conductor disposed above the ground plane. The inner conductor forms a high-frequency patch for receiving radio waves at an upper frequency band. The antenna further includes an outer conductor surrounding the inner conductor. The outer conductor and the inner conductor collectively form a low-frequency patch for receiving radio waves at a lower frequency band. The antenna further includes a filter disposed between the inner conductor and the outer conductor. The filter is configured to at least partially block electrical signals at the upper GNSS frequency band and to let pass electrical signals at the lower GNSS frequency band.
