A multiband vehicular telephone antenna includes a ground plane 22, a patch radiator 20 parallel to it, and electrical short 26. The patch 20 has a feed point for applying a signal to, or receiving a signal from, the antenna. Patch 20 also has apertures, through each of which passes a respective elongate conductor 28 that is connected to the ground plane. The presence of the elongate conductors produces a second resonant frequency band in the antenna. Further resonant frequency bands can be added to the antenna by adding further elongate conductors of corresponding lengths. |
