Abstract
An apparatus comprising an enclosure for an antenna arrangement including physically integrated parts including a first part of relatively dense, injection moldable plastic and a second part of less dense, injection moldable plastic. The first part and the second part are contiguous.
Claims19
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.

A system comprising:
- an enclosure comprising:
- a first part of first injection moldable plastic;
- a second part of second injection moldable plastic, 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 first part defines a skeleton having one or more voids, and the second part infills at least some of the one or more voids of the skeleton;
- 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;
- and
- an antenna arrangement comprising one or more antenna radiators closer to the second part of the enclosure than the first part, wherein the one or more antenna radiators are configured such that a main lobe of a radiation pattern formed thereby passes through the second part,
- wherein the second part forms a protective window for the antenna arrangement and is more transparent than the first part to electromagnetic radiation at an operational bandwidth used by the antenna arrangement and is opaque at optical frequencies, and wherein the plateable plastic provides a feed point or a ground point for one or more of the 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.

A method for manufacturing an enclosure for an antenna arrangement comprising multi-shot injection molding, the method comprising:
- creating a first part of first injection moldable plastic with a first shot of the multi-shot injection molding;
- creating a second part of second injection moldable plastic with a second shot of the multi-shot injection molding;
- and creating
- 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 electromagnetic radiation at an operational bandwidth used by the antenna arrangement, 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, the first part has a higher Youngs Modulus than the second part, 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.
