Claims21
A method of making an antenna radome for a base station antenna, wherein the antenna radome comprises a body generally in an elongated shape, the body extending in a longitudinal direction and comprising an interior space penetrating through the body along the longitudinal direction, wherein at least a portion of the body is integrated with a PIM guard structure or FSS structure, wherein the method comprises:
- providing an extrusion device, wherein the extrusion device comprises a forming mold having a cavity and a core positioned in the cavity of the forming mold, a gap exists between the forming mold and the core, and the gap has a cross-section substantially corresponding to a cross-section of the antenna radome to be formed;
- and
- supplying a first material and a second material to the extrusion device via different openings respectively to integrally form the antenna radome, wherein the first material is used for forming the antenna radome, and the second material is used for forming the PIM guard structure or FSS structure.
A method of making an antenna radome for a base station antenna, wherein the antenna radome comprises a body generally in an elongated shape, the body extending in a longitudinal direction and comprising an interior space penetrating through the body along the longitudinal direction, wherein at least a portion of the body is integrated with a PIM guard structure or FSS structure, wherein the method comprises:
- supplying a first material to an extrusion device to extrude an initial body of the antenna radome, the initial body including a cavity structure formed of the first material;
- arranging a second material for forming the PIM guard structure or FSS structure within the cavity structure;
- and
- extruding the cavity structure inwardly from both sides of the cavity structure at a predetermined temperature and pressure, such that the first material and the second material are bound to one another.
A method of making an antenna radome for a base station antenna, wherein the antenna radome comprises a body generally in an elongated shape, the body extending in a longitudinal direction and comprising an interior space penetrating through the body along the longitudinal direction, wherein at least a portion of the body is integrated with a PIM guard structure or FSS structure, wherein the method comprises:
- supplying a first material to an extrusion device to extrude a first portion of the antenna radome;
- forming a second portion comprising a PIM guard structure or FSS structure;
- and
- fixing the first portion and the second portion together.
An antenna radome for an base station antenna, comprising a body generally in an elongated shape, the body extending in a longitudinal direction and comprising an interior space penetrating through the body along the longitudinal direction, wherein a PIM guard structure or FSS structure is integrated within at least a portion of a wall of the body, the PIM guard structure is configured to prevent the base station antenna from interfering by an external PIM source, and the FSS structure is configured to allow signals in a first frequency range to pass through and not allow signals in a second frequency range different from the first frequency range to pass through.
