Description

Small size antennas have been continuously developed for mobile communications. Spherical Helical Antenna properties were investigated in many cases for better performance. While many desirable characteristics were discovered such as circular polarization over a broad beamwidth and no-sidelobe radiation patterns, the smaller and more compact size of the spherical helix also offers some advantages over the conventional cylindrical helical antenna under certain situations. In this research, we investigated the properties of Double Spherical Helical Antenna which has double spherical windings of different lengths and diameters for better gain, polarization and range. Our goal was to develop this antenna with minimum size to be used for wireless communications, for optimum efficiency and lower cost. The performances of the miniaturized antenna constructed were tested, evaluated, and compared to those of traditional antenna structures.
