  • Dielectrically loaded antenna and radio communication apparatus
    Patent number: 8599101
    Abstract: A radio communication apparatus including: (a) a backfire dielectrically loaded antenna for operation at a frequency in excess of 200 MHz comprising: an electrically insulative dielectric core of a solid material having a relative dielectric constant greater than 5 and having an outer surface including oppositely directed distal and proximal surface portions extending transversely of an axis of the antenna and a side surface portion extending between the transversely extending surface portions, the core outer surface defining an interior volume the major part of which is occupied by the solid material of the core; a three-dimensional antenna element structure including at least one pair of elongate conductive antenna elements disposed on or adjacent the side surface portion of the core and extending from the distal core surface portion towards the proximal core surface portion; a feed structure in the form of an axially extending elongate laminate board comprising at least a transmission line section acting a
