摘要

A wide-band circularly polarized reconfigurable antenna based on a purewater dielectric patch antenna is proposed. By changing the shape of purewater in the plexiglass container symmetrically, the circularly polarized statesof the antenna can be switched. And the available bandwidth of right-hand circularpolarization and left-hand circular polarization remain unchanged. Theinterface between pure water and air with a great difference in relative dielectricconstant is equivalent to an electrical wall. When feed with an L-shapedmetallic probe, the axial ratio of a wide band can be formed, and the impedancebandwidth of antenna can be fully utilized. Under the two circularlypolarized states of the antenna, the measured results show that the 3-dB axialratio bandwidth is above 24.4% for |S_(11)| < 10 dB, the radiation efficiency isconcentrated at 58%–71%, and the maximum gain reaches 3.5 dBi.
