Abstract

A new kind of machinable composite plate was developed for microwave antenna in this paper, in which ceramic powder of CaO-Li₂O-Ln₂O₃-TiO₂ was mixed with PTFE polymer in different proportions. It was showed that the permittivity of the composite plate was enhanced from 4 to 15 with the increasing content of ceramic powder; meanwhile, the quality factor was maintained at 1000GHz. The antenna was obtained with the composite plate which was machined to suitable size and covered with copper electrodes. The antenna´s bandwidth was about 60MHz and standing wave ratio was near 1.12.
