ABSTRACT

This study presents the design theory of the patch antenna of the fed inset patch method and proposes a configuration of the fed inset patch antenna which have a unidirectional radiation pattern with a bandwidth of 1% - 5% designed at the frequency of 2.42GHz and a gain of 6dBi. There are several ways to feed the patch antenna, and the fed inset patch antenna is fed through a microstrip feed line connected to a particular point in the patch. The measured input impedance can be controlled by changing the position at which the microstrip is connected to the patch antenna. The reflection coefficient above was matched with a 50Ω microstrip line. A patch antenna with linearly polarized insertion feed is constructed and its performance is analyzed through suitable simulation and the analyzed results. The inserted microstrip patch antenna was designed and simulated at a resonant frequency of 2.42 GHz. The input return loss was -21.05 dB and the gain was 4.68 dB. The proposed design has a simple antenna structure and can be easily configured at low cost. The simulation results show that the antenna can be regarded as a candidate for various applications in the ISM band because of its good electrical performance.
