摘要： The present invention relates to an RF antenna structure that includes a planar structure and a loading plate, such that the planar structure is mounted between a ground plane and the loading plate to form an RF antenna. The loading plate may be about parallel to the ground plane and the planar structure may be about perpendicular to the loading plate and the ground plane. The loading plate may allow the height of the RF antenna structure above the ground plane to be relatively small. For example, the height may be significantly less than one-quarter of a wavelength of RF signals of interest. The planar structure may include two conductive matching elements to help increase the bandwidth of the RF antenna structure.

摘要： An antenna array may be constructed using a plurality of tubes of electrically conducted material in conjunction with an additionally electrically conductive component which covers the front faces of tubes and at least part of the sides. Between the structures, a further electrically conductive material may be placed separated by dielectric material, and may be used to provide radiating elements and a feed structure by producing stripline structures. This structure is thereby able to reduce cavity back slots fed with triplate stripline along the sides of the tubes. This structure, particularly when made from plastics material, is low in complexity and cost and lightweight. These features overcome many of the disadvantages of the existing designs.

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： Embodiments of the invention relate to wireless communications networks, and more specifically to an antenna apparatus for cellular wireless systems. Increasing data capacity of cellular wireless systems places increasing demands on the capacity of the two way connection, known as backhaul, between a cellular base station and a telecommunications network such as the PSTN backhaul, since this is the connection that has to convey the wireless-originating traffic to its destination, often in an entirely different network. Known backhaul links include leased lines, microwave links, optical fibre links or radio resources for relaying backhaul traffic between base stations. The fixed line solutions are expensive to implement and maintain, while the radio solutions antenna configurations that are not ideal for relaying data between base stations. In embodiments of the invention, communication between base stations occurs in a first timeslot by use of a first antenna system and communication between a given base station and a user equipment occurs in a second timeslot using a second antenna system. The benefit of this method is that the first antenna system can be optimised for use in communication between base stations, whereas the second antenna system can be optimised for communication with user equipment which preferably occurs within the area of cellular wireless coverage of the sector served by the second antenna system.
