Abstract : In a world where the information is moving faster and faster, it is important to be able to stay connected continuously. Some new solutions for air transport connectivity are in development thanks to the rise of satellite communications. This thesis work is part of an electronically steerable antenna array project, developed as a solution to achieve In-Flight Connectivity in Ka-band. A state- of-the art review on electronically steerable antenna arrays is also presented. In these arrays, each radiating element needs a specific amplitude and phase to obtain a scanning beam by adding their contribution. This thesis focus on the design of a GaAs MMIC chip inclusion two functions: a phase shifter and a variable-gain low-noise amplifier. The simulation and measurement results are presented for these two functions.
