A broad band communications antenna includes a baseplate which has a conductive layer that includes at least one coupler opening. A stripline network is provided adjacent the conductive layer in the region of the coupler openings. At least one conductive patch is arranged opposite the baseplate. The baseplate and the patch are arranged in a conductive housing which is provided with an open side. The baseplate is arranged adjacent the bottom of the housing and therefore farthest from the open side. One or more lugs are provided on the open side of the housing for reducing the open cross-sectional surface of the housing when the open side is seen from above.

The broadband communications antenna as claimed in claim 1, wherein the size of each lug does not exceed 10 percent of the size of the patch. 6. The broadband communications antenna as claimed in claim 1, wherein, when a plurality of lugs is provided, the lugs cover the open side of the housing only to such an extent that they do not cover a the patch in a plan view of the open side. 7. The broadband communications antenna as claimed in claim 1, wherein a material whose permittivity is essentially equal to 1.0 is located between the baseplate, on which the conductive layer and the stripline network are located, and the patch. 8. The broadband communications antenna as claimed in claim 1, wherein the conductive layer which is located on the baseplate substantially covers the housing bottom, without being conductively connected to the side walls of the housing. 9. The broadband communications antenna as claimed in claim 1, wherein at least one elongated hole is provided in at least one of(i) each of the two opposite sides of the housing and (ii) each bracket, through which the height of each bracket on the housing with respect to the housing bottom is settable by means of a nut and bolt connection. 10. A broadband communications antenna having a baseplate which has a conductive layer having at least one coupling opening, with a stripline network being provided at a short distance from the conductive layer in the region of the coupling openings, with at least one conductive patch being arranged opposite the baseplate, with the baseplate and the patch being arranged in a conductive housing which has one open side, and with the baseplate being arranged closest to a housing bottom and thus furthest away from the open side, wherein one or more tugs are provided on the open side of the housing and reduce the size of the opening cross-sectional area of the housing in a plan view of the open side, wherein:the housing is rectangular;a lug is arranged centrally on a side surface of each of four sides of the housing;at least one elongated hole is provided in at least one of(i) each of two opposite side surfaces of the housing and (ii) each bracket provided outside the housing on two opposite side surfaces thereof, through which the height of each bracket on the housing with respect to the housing bottom is settable by means of a nut and bolt connection. 11.
