Abstract
In this paper, we present a study to correct the results of measurements carried out in non-anechoic chamber. This study will be conducted in two scenarios. The first scenario is taking antenna measurement data in anechoic chamber that will be used as reference data. The second scenario is taking antenna measurement data in non-anechoic chamber, which is a regular room without absorber. The measurement data on the second scenario will be processed using FFT-Based Method, transformation data from frequency domain to time domain (Inverse FFT) and transformation data from the time domain to the frequency domain (FFT). The data on second scenario contain reflected waves, which have more delay time than direct wave. We will remove or compensate the reflected wave with FFT-Based Method. Furthermore, the corrected data will be validated with reference data obtained from the first scenario. The result of this paper is pattern which has been reconstructed with FFT-Based Method and validated with reference data. This paper described a correction of the radiation pattern measurement at frequency range of 2 to 3 GHz, i.e. 2.025 GHz, 2.545 GHz, and 2.975 GHz.
