ABSTRACT:
A circularly polarized antenna has bays stacked at spacings of less than one wavelength in order to have a broadband SWR characteristic and to minimize radiation along a supporting mast axis. Vertical stubs are used to increase the circularity of the horizontal pattern and to improve the axial ratio.
