摘要：

This study presents an ultrawideband (UWB) slot antenna with a dual-circular (left- and right-hand) circular polarization. The presented circularly polarized (CP) antenna involves 45 degrees oriented patches cooperating with I- and L-shaped stubs fed by a directional coupler. Using a directional coupler produces orthogonal electric fields to generate CP operation, and as a result of the cooperation between patches and stubs, antenna CP performance is improved. The fabricated antenna, including two microstrip ports, occupies an area of 50 x 50 x 1.016 mm3. By stimulating each antenna port independently, it is possible to obtain right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP). The experiments show that the antenna being presented has an operating frequency of 116.14% (2.87-10.82 GHz) and an axial ratio bandwidth of 33.97% (7.11-10.02 GHz). Furthermore, a stable radiation pattern was also measured for the antenna, which had a maximum gain of 2.77 dBic in the operating frequency band.
