  • Multi-band cellular basestation antenna
    Patent number: 6211841
    Abstract: The present invention relates to a multi-band cellular basestation and in particular relates to antennas for such basestations. There is a growing need for mult-band basestation antennas for mobile communication systems, to serve existing 2nd generation systems, and emerging third generation systems. For example, GSM and DCS1800 systems currently coexist in Europe, and emerging 3rd generation systems (UMTS) will initially have to operate in parallel with these systems. The present invention provides a dual/triple/multi-band performance cellular basestation antenna having a shared aperature, having a first set of radiating elements operable at a first frequency range; a second set of radiating elements operable at a second frequency range; wherein the first set and second set of radiating elements are arranged in an interleaved fashion.
