Recent studies have introduced various antenna designs that leverage tightly coupled dipole arrays and other configurations to achieve ultra-wideband performance. For instance, a millimeter-wave ...

This is a wideband antenna called a log-periodic, and it’s an array of dipoles of different frequencies. Yet again if you can estimate the size of each dipole it’s possible to work out the ...

The YECT004W1A is an ultra-wideband 5G external dipole antenna designed for terminal mounting, offering backward compatibility with 4G, 3G, and 2G networks, as well as support for LTE Cat-M and NB ...
