PROJECT TITLE :

Shunt-Excited Sea-Water Monopole Antenna of High Efficiency

ABSTRACT:

Dynamic-type sea-water monopole antenna of high efficiency is presented by using a new shunt-excited feeding structure. The shunt-excited feeding structure is principally fashioned by a conducting tube and a Gamma-shape ( -form) feeding arm connected to the conducting tube close to the prime. Identical circuit model and ANSYS HFSS software are utilized in the analysis and design of the ocean-water monopole antenna. In order to verify the validity of our style concept, two prototypes of shunt-excited sea-water monopole antennas are designed and fabricated: static-sort and dynamic-kind. Measured results of the two fabricated antenna prototypes are in moderately sensible agreement with simulated ones, that demonstrates that the proposed shunt-excited feeding structure offers a great potential for designing high-potency dynamic-sort ocean-water monopole antennas.
