Ključne riječi: antenna over sea; radiation pattern measurement setup; vertical half-wave dipole
Sažetak:
Radiation pattern of a commonly used vertical half-wave dipole was measured over sea. A compact setup was designed and produced based on a shallow pool filled with sea water, defining the propagation path entirely over sea. Antenna under test transmitted a wave across the pool towards the receiving antenna that measured the field strength in various positions, to obtain the radiation pattern of the transmitting antenna over sea. Due to constrictions in the setup dimensions, the working frequency was chosen in GHz range, namely 2.48 GHz. The results are however scalable to lower frequencies. The patterns obtained by preliminary measurements for vertical dipole raised by 1lambda and 2lambda above sea surface are in good accordance with the patterns obtained by NEC simulation.
