Title:
A WIDEBAND MICROSTRIP ELEMENT FOR ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/1999/066594
Kind Code:
A1
Abstract:
A wideband microstrip element for array antenna has a microstrip feed line, a dielectric layer, a metal ground plate, a coupling window, a first patch and its dielectric substrate, a second patch and its dielectric substrate. Hollow metal pedestal and dielectric abutments are mounted on a metal ground plate in sequence, the dielectric substrate of the first patch is arranged on an opening of the hollow metal pedestal and the dielectric substrate of the second patch is fixed on dielectric abutments, forming resonance cavity between metal ground plate and first patch and between rfirst patch and second patch, respectively. The antenna array described above has characteristics of wide operation frequency band, higher gain, high efficiency, simple structure and easy fabrication.
