摘要：The study of the excitation of two circular slot antenna modes fed by coupling effect for bi-band or broadband applications is proposed in this paper. The different configurations of circular to semicircular antenna with rectangular slot having 1 mm to 12 mm length, lead respectively to the central frequencies of 1.83 and 4.3 GHz; 1.83 and 3.48 GHz, 1.83 and 2.49 GHz, for which the device can be used as a bi-band antenna. For broadband applications, a prototype having rectangular slot of 14.5 mm length exhibits a 43% bandwidth measured by the 10 dB return loss, a pic of realized gain equal 3.5 dB and radiation efficiency between 80 and 87% in the 1.72-2.66 GHz adapted band.
