Nowadays, the developments of wireless communication fields are widely used. One of them is the usage of the antennas in data transmission between the receive antenna and the transmit antenna. Active Integrated Antenna (AIA) is a new technology that integrates the passive antenna element with active device in a single substrate. In this project, an inset feed microstrip patch antenna is integrated with a Low Noise Amplifier (LNA) to produce an AIA system. The purpose of this project is to investigate in terms of active and passive performance of the antenna. Indeed, this microstrip patch antennas are known to be easy to be integrated with active devices. This microstrip patch antennas will directly be integrated to the transistor, producing gains and low noise. Commonly, antennas that have been designed are not integrated directly to the active devices, causing high noise but with the AIA approach it could reduce the losses. This Low Noise Active Integrated Antenna (LNAIA) is resonated at 2 GHz that used transmission line feeding method with impedance matching at 50 ohm. The matching technique is important in designing the LNA. Besides that, this AIA’s have many advantages such as less cost, smaller size and good for radiation characteristic for microwave wireless communications.
