This final thesis carried out design and realization of the microstrip array antenna on the 2.3 GHz frequency in order to be used for the application of WiMAX Subscriber Station for indoor use. The microstrip antenna was chosen because it was considered most suitable for microwave communication and has several advantages compared to other type of antenna. The microstrip antenna fulfils the requirements required by present technology that is it’s low cost production, light weight as well as its relatively small dimensions. The 2.3 GHz frequency was chosing according to the allocation frequency for WiMAX application in Indonesia. The microstrip array antenna which will be realized is designed so that it will operate on the 2.3 – 2.39 GHz which has a minimum gain of 10 dBi and has a circular polarization. In this final thesis, Computer Aided Design (CAD) software, is used to carry out design and simulation of the antenna. The design which is going to be implemented is rectangular patch with microstrip line feeding technique. The realization of the design using FR-4 substrate by the photo etching method. The gain obtained during measurement amounted to 9.619 dBi on the 2.362 GHz frequency. The measurement bandwitdth at VSWR< 2 is 139 MHz at the frequency range of 2.270 GHz – 2.409 GHz or 5.88%. The VSWR score resulted from measurement on resonation frequency 2.362 GHz amounted 1.023. The LHCP circular polarized antenna with an acceptance variant level maximum power to the amount of 2.825 dBm to all the corners of acceptance.
