This paper presents a transmission-line structure suitable for micromachining technology. The structure is an air-filled square coaxial cable, which is very low loss and has been designed in order to utilise current manufacturing processes. This transmission line demonstrates that such a structure can be designed to cover very wide bandwidth. As the cable is air filled, the centre conductor needs to be supported and this is accomplished by attaching quarter-wavelength stubs to the ground. The design method of such a cable is presented in detail and the results of an X-band component are presented.
