Abstract: Antenna with broad bandwidth,wide beam and circular polarization performance are needed in spaceborne,airborne and terrestrial application.A novel double-ring antenna is(presented).The structure of this antenna is also very simple.The measurement of radiation(characteristics) is in good agreement with simulation results.The gain of low elevation angle can be improved by adding a metallic reflector,and the input impedance and the axis ratio can also be(improved).
