WebCell Phone Antennas The wavelength of the received signal is the primary fac-tor in the design and manufacture of Antennas. In fact, all antennas can receive any electromagnetic signal re-gardless of its wavelength, but the received signal is very weak if the antenna is not proportional to the re-ceived wavelength. Types of Antennas used in Cell 6 WebThe cell phone antennas are often linearly polarized and the polarization of base tower antennas is often vertical, but other polarization directions are also used. ... For the wavelength of 14 cm (2.1 GHz), reducing the path by only 7 cm will lead to moving from a signal being out of phase to a signal being in phase. Of course, this example is ...
