Design of a Circularly Polarized Broadband Slot Antenna for Base

In this paper, a wideband MIMO antenna is presented, arranging four drop-shaped slot antennas perpendicularly one to each other, but placed in different layers

For instance, a slot antenna with a tunable bandwidth utilizing graphene inks can achieve an operating bandwidth from GHz to 6 GHz, with a

slot it 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

slot valve Regardless, these dual band and triple band slot antennas are large in size, most of the wireless applications minutarized antennas are needed
