PROJECT TITLE:

A Low-Profile Wide-Beamwidth Circularly-Polarized Antenna via Two Pairs of Parallel Dipoles in a Square Contour

ABSTRACT:

A circularly polarized antenna with wide axial-ratio beamwidth is presented by putting two pairs of parallel dipoles in a very square contour. Firstly, our study demonstrates that circular polarization will be achieved at the broadside by setting a 90$^circ$ part distinction between the vertical and horizontal paired-dipoles. Secondly, the principle of wide-beamwidth circularly-polarized radiation is described underneath the similarity in polar and azimuthal radiation pattern for a pair of parallel dipoles. After the spacing between 2 parallel dipoles is studied, the similar radiation patterns in these 2 orthogonal planes are derived. As such, a large-beamwidth circular polarization can be achieved by putting the 2 pairs of parallel dipoles vertically and horizontally whereas setting a 90$^circ$ phase difference between them. In final, a circularly-polarized printed antenna is intended and fabricated on a single dielectric substrate. The 2 arms of its four dipoles are fashioned on the lower and higher interfaces of the substrate, and they are excited by a 1-to-4 probe-to-microstrip feeding network. Experimental results show sensible agreement with simulated ones in terms of radiation pattern/gain, axial ratio and came back loss. In explicit, the three-dB axial ratio beamwidth at the central frequency of one.half dozen GHz has extended to 126$^circ$ in an angular range from $-sixty three^circ$ to $+sixty three^circ$. The fabricated antenna exhibits an occasional-profile property with the height of zero.0043 free-area wavelength.
