Abstract :
In this paper, we report the design, development and fabrication of high performance Ka-band square and circular micromachined patch antenna using post-CMOS compatible process technology. The main emphasis of this paper is to use RF sputtering as potential metal-dielectric film deposition-process for rapid prototyping of many antenna structures in the absence of access to a well-established MEMS foundry. The fabricated antenna resonated at 35 GHz with 4.0 % impedance bandwidth
