The ultra-wideband, omnidirectional circular ring antenna has a height of 0.047 times the low-frequency wavelength and a width of 0.19 times the wavelength, offering an impedance bandwidth of 12:1.
A circular patch antenna based on open elliptical-ring slots and shorting vias with conical radiation patterns is proposed. Fed by the coaxial probe at the center of the circular patch, the proposed ...
The ultra-wideband, omnidirectional circular ring antenna has a height of 0.047 times the low-frequency wavelength and a width of 0.19 times the wavelength, offering an impedance bandwidth of 12:1.
Omnidirectional antennas are engineered to radiate or receive electromagnetic energy uniformly in the horizontal plane, making them indispensable for applications where consistent azimuthal coverage ...
