Abstract
A novel compact and wideband circularly polarized (CP) crossed dipole antenna is presented. To realize CP radiation, a new design concept of using coupling stub is first illustrated. The coupling stub is equivalent as a combination of a dipole-c and dipole-y. The dipole-c not only couples proper energy from the x-axis arranged driven dipole-x to the orthogonally arranged dipole-y, but also provides quadrature phase delay to the dipole-y. Therefore, CP radiation is realized for the presented configuration. To improve the input impedance caused by the strong coupling, a long narrow strip is incorporated for the enhancement of impedance bandwidth. Based on the design concept, a compact and wideband CP antenna by using the coupling stub and stepped square loop is developed to further increase the operation bandwidth and realize stable radiation. The designed antenna was finally fabricated for performance verification. Both the simulation and measurement show that the developed antenna can have a wide overlapped impedance and AR bandwidth from 1.1 to 1.74 GHz with a compact radiator size. In addition, stable antenna gain and radiation patterns are achieved for wireless communications.
