Penelitian ini melakukan perancangan dan realisasi sebuah antena, yang terdiri atas susunan empat mikrostrip patch persegi panjang yang dicatu secara seri menggunakan distribusi Dolph-Tchebyscheff. Antena ini dirancang untuk dapat bekerja pada frekuensi 2,3 GHz karena frekuensi tersebut digunakan untuk Worldwide Interoperability for Microwave Access (WiMAX) sehingga antena ini dapat digunakan untuk aplikasi WiMAX. Makalah ini menjelaskan proses desain, realisasi, hingga pengukuran. Desain dimulai dengan perhitungan secara teoritis berdasarkan teori desain antena mikrostrip dan teori distribusi Dolph-Tchebyscheff. Kemudian, hasil perhitungan tersebut dioptimalisasi dengan bantuan suatu perangkat lunak desain antena hingga memperoleh karakteristik antena sesuai dengan spesifikasi yang diinginkan. Keluaran akhir dari penelitian ini adalah sebuah prototipe antena susunan mikrostrip patch persegi panjang empat elemen yang bekerja pada frekuensi 2,3 GHz. Parameter antena, seperti VSWR, polarisasi, pola radiasi, bandwidth, dan gain, juga diukur. Pada akhir proses penelitian ini, hasil pengukuran dibandingkan dengan hasil perhitungan teoritis dan simulasi.
Antenna array consist of four rectangular microstrip patch antennas with serial feeding using Dolph-Tchebyscheff distribution will be design in this research. This antenna works at 2.3 GHz because the frequency is used for Worldwide Interoperability for Microwave Access (WIMAX) so that the antenna can be applied for WIMAX applications. This paper decribes the process design, realization, and measurement. The design is started with theoritical calculations based on the theory of micristrip antenna design and theory of Dolph-Tchebyscheff distribution. Then, the result of the calculations are optimized using antenna design software to obtain the antenna characteristics according to the desired specifications. The output of this research is a prototype of rectangular microstrip patch antenna array which can work at 2.3 GHz. The antenna parameters, such as VSWR, polarization, radiation pattern, bandwidth, and gain, are measured. At the end of the process, the measurement results are compared with the theoritical calculation and simulation results.
