ANTENNA ASSEMBLY
First Claim
1. An antenna assembly for operation at a frequency in excess of 200 MHz, comprising the combination of a dielectrically loaded antenna and a housing, the housing incorporating a connector for coupling the antenna to host equipment, wherein:
- the antenna comprises an insulative core which has an outer surface and is shaped to define a central antenna axis, at least one conductive element on or adjacent the core outer surface, and a laminate board on the central axis, the outer surface of the core including proximal and distal surface portions oriented transversely with respect to the axis and a side surface portion surrounding the axis and extending between the proximal and distal surface portions, and the laminate board extending proximally from the proximal core surface portion;
the housing comprises a housing body which forms a hollow conductive shield for the laminate board, and is centred on the antenna axis, the housing body having a distal recess which is bounded by a distal housing rim and is shaped and dimensioned to house a proximal portion of the antenna with the distal rim surrounding and engaging the antenna side surface portion, a side wall which extends proximally from the housing rim to surround the axis thereby to enclose an interior space containing the laminate board, and a proximal connector portion housing a signal contact insulated from the conductive shield and connected to a signal conductor of the laminate board;
and the housing is shaped to provide a mounting surface which, in a cross-sectional plane perpendicular to the axis, defines a periphery of an area in the said plane which area is at least as great as the cross-sectional area of the said proximal portion of the antenna.

Abstract
Among the embodiments disclosed herein is an antenna assembly comprising the combination of a dielectrically loaded antenna and a housing, the housing incorporating a connector for coupling the antenna to host equipment. The antenna comprises an insulative core which has an outer surface and is shaped to define a central axis, and a laminate board on the central axis, the laminate board extending proximally from a proximal core surface portion oriented transversely with respect to the axis. The housing comprises a housing body which forms a hollow conductive shield for the laminate board, and is centred on the antenna axis, and the housing is shaped to provide a mounting surface which, in a cross-sectional plane perpendicular to the axis, defines a periphery of an area in the said plane which area is at least as great as the cross-sectional area of the said proximal portion of the antenna.
