1. A millimeter-wave radio system, comprising: an antenna body made from a single piece of material, the antenna body comprises a reflector region and a waveguide region; anda radio receiver mounted on a printed circuit board that comprises a laminate waveguide structure, wherein the printed circuit board is mechanically fixed to a section of the antenna body that constitutes the waveguide region such that the printed circuit board is mechanically held by the section of the antenna constituting the waveguide region and such that the laminate waveguide structure together with the waveguide region create a concatenated waveguide;wherein the system is operative to: (i) reflect millimeter-waves from the reflector region toward an aperture of the waveguide region, then (ii) guide the millimeter-waves through the concatenated waveguide, and then (iii) feed the radio receiver with the millimeter-waves, in which said reflecting, said guiding, and said feeding are all done in conjunction with the single piece of material. 2. The system of claim 1, wherein the radio receiver comprises a probe located above the laminate waveguide structure or inside the laminate waveguide structure, and the probe is operative to transform the millimeter-waves into a corresponding electrical signal. 3. The system of claim 2, wherein the probe is printed on one lamina of the printed circuit board. 4.

The system of claim 1, wherein the printed circuit board is a low temperature co-fired ceramic. 6. The system of claim 1, wherein the printed circuit board is mechanically fixed to the waveguide region such that the substrate directly touches the waveguide region at least at one point. 7. The system of claim 1, wherein the printed circuit board is mechanically fixed to the waveguide region via a coupling surface, such that the substrate does not necessarily directly touch the waveguide region. 8. The system of claim 7, wherein the thickness of the coupling surface is less than 5 millimeters. 9. A millimeter-wave radio system in a form of a cassegrain antenna, comprising: an antenna body made from a single piece of material, the antenna body comprises a reflector region and a waveguide region, in which the waveguide region is operative to guide millimeter-waves from a location in front of the reflector region, to a location behind the reflector region;a radio receiver mounted on a substrate and located behind the reflector region, wherein the substrate is mechanically fixed to a section of the antenna body that constitutes the waveguide region such that the substrate is mechanically held by the section of the antenna constituting the waveguide region; anda sub-reflector located in front of the reflector region;wherein the system is operative to: (i) reflect the millimeter-waves from the reflector region toward the sub-reflector, (ii) reflect the millimeter-waves from the sub-reflector to an aperture of the waveguide region located in front of the reflector region, (iii) guide the millimeter-waves through the waveguide region, and (iv) feed the radio receiver with the millimeter-waves, in which said reflecting, said guiding, and said feeding are all done in conjunction with the single piece of material. 10. The system of claim 9, wherein the sub-reflector is connected to the waveguide region via a second waveguide, and the second waveguide together with the waveguide region form a feed. 11. The system of claim 9, wherein the antenna body doubles as a part of a box, and the box is operative to house electronic components comprising the radio receiver. 12. The system of claim 11, wherein the part of the box comprises a radiator fins region operative to remove heat from the radio receiver, and the radio receiver is thermally coupled to the part of the box via the waveguide region and the substrate. 13. The system of claim 9, wherein the reflector is operative to focus millimeter-waves toward the aperture. 14. The system of claim 9, wherein the single piece of material is formed using metal injection molding. 15. The system of claim 9, wherein the single piece of material is formed using a milling machine. 16. The system of claim 9, wherein the single piece of material is made from a material selected for a group consisting of aluminum and magnesium.
