“…Turnstile antennas can be oriented for linear or circular polarization. The turnstile antenna can be expanded into a double crossed-dipole [22] or Yagi [23] antenna array for less nulls in the radiation pattern for NOAA satellite reception. Due to the length of the dipoles, the crossed-dipole could interfere with the propeller downwash on a UAS, so this design was avoided to help preserve rotor lift.…”

Thesis xii I would like to thank Dr. Alan J. Fenn and members from Group 86, MIT Lincoln Laboratory, for providing advice on designing an impedance matched circuit for the VHF frequency range. I would like to thank my advisor, Professor Hanumant Singh, for allowing me to conduct this research in his lab group and providing me the tools and resources to complete my research successfully. I would like to thank members of Group 107, MIT Lincoln Laboratory, for providing technical mentorship and guidance.
