Also, from Figures 8 to 19 it is apparent that the spiral slot shows elliptical polarisation. The axial ratio of the antenna is about 10 dB across the entire frequency band which is caused by the phase difference in the spiral arms.
Offering either horizontal or elliptical polarisation, the nonpressurised DLP-V and pressurised TLP-BB are stand-alone products that feature simple mechanical designs for ease of installation.
This horizontally polarised antenna may be configured to include varying levels of vertical polarisation with results ranging from small amounts of elliptical polarisation.
