    The design of the Cerro Chajnantor Atacama Telescope (CCAT) is progressing within the international astronomical community. This thesis examines the feasibility of using CMOS technology to implement a 460 GHz SIW slot antenna for the CCAT Heterodyne Array Instrument. A 46 GHz broadband high-gain SIW slot antenna was designed and tested to verify the SIW slot antenna design procedure. That design demonstrated good agreement between the simulated and measured results. The antenna has a measured gain of 7.8 dBi at 46.2 GHz and bandwidth of 4.72 GHz. Then design of a 460 GHz SIW antenna was conducted in a 65 nm CMOS process. Several methods were used to simplify the design and simulations: an inductor identification layer was introduced to minimize the design-rule restrictions, and an equivalent dielectric layer was calculated to reduce the computational resource for 3D electromagnetic simulations. The proposed antenna has a gain of 0.09 dBi, efficiency of 29.1% and bandwidth of 25.3 GHz.
