As mentioned in Chap.  2, a major cause of frustration to the radio astronomer is the extremely poor angular resolution compared to what is provided in the optical domain. One way to overcome this handicap is the use of interferometers or synthesis telescopes. However, there also remained the desire to extend the frequency range of single reflectors to very high frequencies with as large a size as possible, which would both improve the resolution and widen the available window in the electromagnetic spectrum. It led to activities in the development of mm-wavelength detectors and the realisation of reflector antennas capable of observing at wavelengths as short as 1 mm. This posed new challenges to the structural design engineer and to manufacturing, particularly of highly accurate reflector surface panels. We describe the results of these efforts in this and the following chapter by example of some of the telescopes dedicated to the millimetre- and submillimetre-wavelength range.
