A compact dual polarized 3:1 bandwidth omnidirectional array of spiral antennas
Résumé
A circularly polarized wideband omnidirectional array of spiral antennas is presented. It covers the frequency band from 1.2 GHz up to 3.6 GHz while keeping a good S11 and an omnidirectional coverage. This array achieved a dual polarization using left and right hands archimedean spiral antennas. The gain of the array is enhanced using a unique cavity for the entire array and the realized gain is above the maximum theoretical gain of a single spiral antenna.
