Antennas work on resonant frequencies, which require an antenna design that targets the specific frequency range and impedance for the . In current deployment phases below 2.6GHz, 5G requires at least a 4 x 4 downlink MIMO and recommends at least a 2 x 2 uplink MIMO. Reduction in antenna size allows more antennas to be placed in a given area, which then increases the available gain and resolution of the output beam. Devices that will include a 5G-compatible front-end, whether small stations/repeaters or handheld devices, use phased arrays as high . Separate networks avoid interference. An outdoor omni WiFi antenna can be connected in a similar way using a suitably matched coaxial cable with an appropriate connector. In 5G systems, there are two approaches to forming the complete phased array: The number of discrete array elements (patches or parallel arrays) will determine total available gain of the array given its virtual array, as well as the maximum number of users that can be supported through beamforming/multiplexing. The CAD tools and mechanical collaboration features in Altium Designerare essential for designing PCBs and packaging with 5G phased arrays and microstrip patch arrays suporting mmWave wireless systems.
