1. An apparatus comprising an enclosure for an antenna arrangement comprising physically integrated parts, the enclosure comprising:
a first part of first injection moldable plastic;
a second part of second injection moldable plastic; and
one or more further parts proximate the first and second parts and formed of plateable plastic comprising a plastic with an additive enabling the plastic to be plated with metal,
wherein the first injection moldable plastic is more dense than the second injection moldable plastic, the first part and the second part are contiguous, the second part is more transparent than the first part to transmitted or received electromagnetic radiation at an operational bandwidth used by the antenna arrangement, such that an overall radiation efficiency of the antenna arrangement housed within a cavity is not compromised by the enclosure, the first part defines a skeleton having one or more voids, the second part infills at least some of the one or more voids of the skeleton, and the plateable plastic provides a feed point or a ground point for one or more antenna radiators to provide electrical coupling to at least one of: radio frequency receiver circuitry, radio frequency transmitter circuitry, or radio frequency transceiver circuitry.
