摘要： Embodiments of the invention relate to an antenna structure and are particularly suited to array antennas. Conventionally, an antenna of the cavity-backed slot-radiating type comprises a slot formed in an end of an electrically conductive enclosure, which slot may be energised by a radiating element in registration with the slot. A feed network may connect to the radiating element via a transmission line formed by a conductive track on a feed layer located between the enclosure and an electrically conductive cover. A slot is formed in the section of the cover that covers the end of the cavity in which a slot is formed, such that the two slots are of substantially the same size and shape. A problem with this structure is that the cavity is difficult to mould in one piece and it can be difficult to achieve alignment of respective slots; as a result it is relatively costly to manufacture. Also, it is difficult to insert dielectric material into the enclosure to adjust the performance parameters of the antenna. An antenna according to an embodiment of the invention employs an enclosure having an aperture in one end; in preferred arrangements the aperture provides the enclosure with a substantially open end, over which the cover is placed. The cover has a slot therein, of a smaller size than the size of the aperture presented by the open ended enclosure and the slot in the cover then acts as the radiating slot. The benefit is that it is then easier to insert dielectric material into the enclosure and the enclosure is easier to mould in one piece, leading to a potential cost reduction.

摘要： A broadband antenna structure has an electrically conductive enclosure with a closed end, over which a non-electrically conductive cover is placed. A radiating portion of an antenna feed layer comprising a conductive patch antenna element is placed in between the enclosure and the cover. The patch antenna element design is inherently broader band than that of conventional cavity-backed slot-radiating antennas, which are constrained in bandwidth by the need to keep the cavity formed in the enclosure small. The dielectric constant of the dielectric material of the cover reduces the required size of the conductive antenna element. The broadband antenna structure may be connected with an electronic device to form an antenna arrangement in which a portion of the antenna feed layer extends through an opening in a surface of an antenna housing, the portion being within an electronic device enclosure of the electronic device.

摘要： Embodiments of the invention relate to a broadband antenna structure and an antenna arrangement comprising the antenna structure and an electronic device. In one aspect, the antenna employs an electrically conductive enclosure with a closed end, over which a non-electrically conductive cover is placed. A radiating portion of the antenna feed layer comprising a conductive patch antenna element is placed in between the enclosure and the cover. This patch antenna element design is inherently broader band than that of conventional cavity-backed slot-radiating antennas, which are constrained in bandwidth by the need to keep the cavity formed in the enclosure small, so that the column elements may be arranged in an array at substantially half-wavelength spacing. The new design suffers less compromise in terms of bandwidth in achieving the same size constraint. This is achieved in part by the dielectric constant of the dielectric material of the cover reducing the required size of the conductive antenna element, compared to the size that would be required if the radiating portion were covered with a material with the dielectric constant of air. In another aspect, this broadband antenna structure is connected with an electronic device to form an antenna arrangement, wherein a portion of the antenna feed layer extends outside of the antenna housing through an opening in a surface of the antenna housing, said portion being within the electronic device enclosure of the electronic device. Connecting the electronic device directly to the antenna according to embodiments of the invention reduces the amount of coaxial cables needed or eliminates the need for coaxial cables completely. As a result the usual costs associated with coaxial cables, the RF losses introduced by the cables which can compromise the system performance, possible failure of the cables, lease costs for the space the cables occupy and lease costs for large footprint of the building or cabinet housing the electronic device are substantially reduced or eliminated.
