| Abstract | An interferometric array similar to the LOFAR Prototype Station LOPES and to the Eight-meter-wavelength Transient Array ETA is being developed by using active antennas, more specifically thin inverted-V dipole antenna, which is designed to cover the LOFAR frequency range under 100 MHz. This paper presents the design and evaluation of an active antenna for a prototype interferometric array which is being developed at the site of the Southern Space Observatory SSO/CRS/INPE-MCT (29.4°S, 53.8°W, 480m), in São Martinho da Serra, approximately 54 km distant far from the city of Santa Maria, in Rio Grande do Sul state, South of Brazil. The next generation of large telescopes for radio astronomy at low frequency, below 100 MHz, will consist of thousands of wide-band dipole-like antennas. At this frequency range, the sensitivity of a telescope is limited by the Galactic Noise, for this reason a thin inverted-V dipole was combined with a simple active balun in order to provide the necessary sensitivity and a high useable bandwidth. The results show that an active antenna can present a satisfactory performance, although its VSWR varies greatly with frequency. Also, the results are consistent with our recent theoretical analysis, which are according to LOPES and ETA radio telescopes conclusions. Therefore, this instrumentation is adequate to multi-wavelength solar observations. | |||
