The integration of polarization diversity into a uniplanar design is particularly advantageous. Polarization diversity refers to the use of antennas that can receive or transmit signals with different polarization states (e.g., linear horizontal and vertical, or circular left-hand and right-hand). By employing multiple polarizations, the likelihood of signal fading due to multipath propagation is significantly reduced, leading to improved link reliability.作者：S Saleh·2023·被引用次数：31—A novel miniaturized Vivaldiantennausing taperedslotedge with resonant cavity structure forultrawideband applications.
