- Description
This project addresses the analytical design and simulation of two types of millimetre wave antennas: a single patch antenna and a dual frequency antenna. Both antennas are based in the GaAs MMIC multilayer technology and use a coplanar waveguide (CPW) feeding. The analytical design is based in the transmission line (TL) model for microstrip antennas. The simulations are conducted in the 3D electromagnetic (EM) simulator Momentum, which is based in the Method of Moments (MoM). The proposed dual frequency antenna is based in the premise of dividing a microstrip patch in several multiresonators, producing two resonant frequencies by EM parasitic coupling. This particular structure has not been used to provide dual frequency operation in the millimetre wave range, specially combining GaAs MMIC multilayer technology with CPW feeding. A detailed design procedure is developed for the single patch antenna, such that it can be used as a guide for future designs. A parametric study of the single patch antenna is performed to understand the influence of various parameters in the antenna operation. The complete design process led to the successful development of a single patch antenna that works around 35 GHz and a dual frequency antenna that works around 35-50 GHz. Results showed that the combination of GaAs MMICs with CPW feeding can produce efficient antenna designs regarding size considerations. Momentum was successfully used to optimize both antennas with respect to size, resonant frequencies, return loss and input impedance.
