antenna array control circuitry configured to coordinate operation of the first antenna array and the second antenna array dependent on the chosen deployment configuration;

wherein the antenna apparatus is configured to support a plurality of different modes of operation, the plurality of different modes of operation including a relay mode, a point-to-point mode, a point-to-multipoint mode and any combination thereof, and the antenna apparatus being configured to operate in a chosen mode of the plurality of different modes; and

wherein the chosen deployment configuration is chosen in dependence on the chosen mode.

2. The antenna apparatus of claim 1 , wherein:

at the first limit, the first and second antenna arrays are positioned adjacent to each other to face in a same direction; and

at the second limit, the first and second antenna arrays are positioned back-to-back to face in opposing directions.

3. The antenna apparatus of claim 1 , wherein:

the first antenna array is mounted on a first support and the second antenna array is mounted on a second support; and

the first and second supports are coupled by a hinge mechanism, wherein the hinge mechanism defines the common axis of rotation.

4. The antenna apparatus of claim 3 , wherein:

the antenna positioning circuitry is configured to facilitate reciprocating motion of a first end of at least one of the first and second supports along a linear path.

5. The antenna apparatus of claim 4 , wherein:

the antenna positioning circuitry comprises a linear structure;

the antenna apparatus further comprising an attachment member to couple the first end of the at least one of the first and second supports to the linear structure to support the reciprocating motion.

6. The antenna apparatus of claim 5 , wherein the antenna positioning circuitry comprises a motor configured to facilitate the reciprocating motion by causing reciprocating movement of the attachment member along the linear structure.

7. The antenna apparatus of claim 6 , wherein:

the motor is configured to facilitate the reciprocating motion by driving the attachment member to move along the linear structure.

8. The antenna apparatus of claim 6 , wherein:

the linear structure and the attachment member comprise complementary threading; and

the motor is configured to facilitate the reciprocating motion by driving the rotation of at least one of the linear support and the attachment member.

9. The antenna apparatus of claim 5 , wherein:

10. The antenna apparatus of claim 1 , wherein the first and second antenna arrays are configured to be electronically steered.

11. The antenna apparatus of claim 1 , wherein the antenna apparatus is configured for rotation about a further axis parallel to the common axis of rotation.

12. The antenna apparatus as claimed in claim 11 , wherein:

the antenna positioning circuitry comprises a linear structure;

the antenna apparatus further comprises an attachment member to couple the first end of the at least one of the first and second supports to the linear structure to support the reciprocating motion; and

wherein the antenna apparatus has a length in the direction of the linear structure, and has a rotation mechanism to facilitate rotation of the antenna apparatus about a centre point of the length to cause rotation about the further axis.

13. The antenna apparatus of claim 1 , wherein the first and second antenna arrays are configured to operate using the same frequency channel or different frequency channels in dependence on the chosen deployment configuration.

14. A method of operating an antenna apparatus comprising a first antenna array and a second antenna array, the method comprising:

moving the first antenna array relative to the second antenna array about a common axis of rotation to facilitate positioning of the first and second antenna arrays in a chosen deployment configuration between a first limit and a second limit; and

coordinating operation of the first antenna array and the second antenna array dependent on the chosen deployment configuration;

wherein the antenna apparatus is configured to support a plurality of different modes of operation, the plurality of different modes of operation including a relay mode, a point-to-point mode, a point-to-multipoint mode and any combination thereof, and the method comprising operating the antenna apparatus in a chosen mode of the plurality of different modes;
