Method to develop a radio frequency communications device with improved performance and a device developed acording to said method

A method for designing a communications device comprising an antenna system to achieve a predetermined radiation performance, the method comprising:

• identifying a frequency, a frequency band, or a plurality of frequency bands in which the communications device is to operate;
• determining a number of antennas within the antenna system to achieve the predetermined radiation performance;
• determining a physical placement for each antenna within the antenna system relative to physical placement of other antennas within the antenna system;
• designing antenna elements for each antenna of the antenna system;
• after a step of designing, testing the antenna system relative to the predetermined radiation performance and if the predetermined radiation performance is not achieved, modifying one or more of the antenna elements;
• after a step of modifying, first retesting of the antenna system relative to the predetermined radiation performance and if the predetermined radiation performance is achieved, designing an enclosure for the antenna system and incorporating the antenna system into the enclosure, and if the predetermined radiation performance is not achieved returning to a step of modifying;
• and
• after incorporating the antenna system within the enclosure, second retesting of the antenna system relative to the predetermined radiation performance, if the predetermined radiation performance is achieved the method for designing the communications device is concluded, and if the predetermined radiation performance is not achieved modifying one or more elements of the enclosure and re-executing a step of second retesting.
