Antennas are divided into two categories: single polarization antennas and dual polarization antennas. In addition to simple single polarization and dual polarization antennas, there are also some special antennas: The UHP S2D antenna is a multifunctional antenna that converts the default single polarization antenna into a dual polarization antenna through modification; The UHP SDB antenna is a dual band antenna that can transmit both conventional and E-Band signals simultaneously. Each frequency band can be Single polarization can also be dual polarization; UHP modular antenna is a new type of composite antenna that can be changed by changing the feed source to change the frequency point, frequency band, or Replace components and switch between dual polarization and single polarization.
