MULTIBAND PLANAR ANTENNA FOR CELLULAR COMMUNICATION
Currently, there is an increased demand for multi-band antennas in cellular communication systems, because. using multiple single band antennas requires a lot of space and is not always possible in mobile devices. The integration of a multi-band antenna into a mobile communication system allows you to take full advantage of the various ranges of communication systems while minimizing the amount occupied by it.The article proposes a quad-band PIF antenna operating in the frequency ranges 824 … 894 MHz (3G UMTS - FDD, BAND 5), 1910 … 1990 MHz (3G UMTS - TDD, BAND 36-37), 2500 … 2690 MHz (4G LTE - FDD, BAND 7) and 3300 … 3400 MHz (4G WiMAX - TDD).
