Wind-Proof Log Periodic Dipole Array for Capturing Solar Radio Bursts

The authors have been designed and developed a wind-proof Log Periodic Dipole Array (LPDA) at Kalyani, West Bengal for recording solar bursts in the frequency range 50 to 300 MHz. From a consideration of design parameters, the paper elaborately discusses about the wide angle solar array spectrograph with an emphasis on basic positioning of two static antennas to form a uniform wide angle beam. Design details of the log periodic antennas as well as the artificial convex ground structures are presented with important specifications and the physical properties of the LPDA.
