| 摘要 |
The invention relates to an antenna (ANT) comprising a radiating element (ELR) mounted above a substantially flat reflector. The radiating element (ELR) is of the broadband type and substantially flat. The reflector (SHI) has a metal periodic network (RS) of regular patterns in two dimensions, and a ground plane (PM) formed by the bottom face of the surface of the high impedance type. Each pattern of the periodic network (RS) is respectively connected to the ground plane (PM). The antenna having a thickness of the order of 1/13th of the wavelength at the minimum frequency of the frequency band.
