300-800 MHz LNA-Integrated Log-Periodic Dipole Antenna for BURSTT
BURSTT (Bustling Universe Radio Survey Telescope in Taiwan) is an array antenna in Taiwan for detecting and localizing Fast Radio Bursts (FRBs). To increase its detection probability, system with wide field of view (FoV), wide bandwidth, and high sensitivity is required. To address these demands, a log-periodic dipole antenna covering 300 to 800 MHz is designed and fabricated. The antenna is with <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\sim 8 \text{dBi}$</tex> gain and beamwidth of 60- and 90-degree for E- and H-plane, respectively. Furthermore, the LNA is placed at the feed point of the antenna to maximize the system sensitivity. Improvement was confirmed by measuring on-sky system equivalent flux density (SEFD).
