Abstract
The Log Periodic Dipole Antenna (LPDA) performance of solar burst monitoring in the range of (45 -870) MHz is presented. This project is under the International Space Weather Initiative (ISWI) program in order to observe the solar activities within 12 hours per day. At the first stage, we make an effort by constructing LPDA that suitable with the criteria, specification and practical enough with 5.45 meter boom length size of the antenna. The rods then were perforated with nineteen (19) elements that were made of aluminum rods. Two (2) rod aluminums type with nineteenth (19) elements that signify different frequencies. The gain of this antenna is 6.67 which is required preamplifier to amplify the signal of the Sun. From the results, we found that the effective temperature of the antenna is 1.3 dB and the temperature of the Sun during that observation is 1578 K. Some suggestions on improving this design are also presented.
