Abstract : A single antenna having hemispherical coverage with circular polarization at very low axial ratio is disclosed. Its pancake structure comprises two stacked microstrip antennas, one atop the other, each fed phase shifted in relation to the other. Used as transmitter or receiver antenna, it replaces conventional hemispherical types with an extremely compact and relatively inexpensive device.
