\"Touchstone<\/a>

Touchstone import to Aytune: 1 - 4 marks the lower GSM bands and 5 - 6 marks the higher GSM band plus UMTS band<\/p><\/div>\n

My IoT M2M Cookbook <\/a>got an update. The mayor news is that everybody who owns a copy of the book will get an export (Touchstone file) out of CST Microwave Studio for import to Atyune.<\/a> Atyune is a free of charge software to generate a matching circuit automatic. The jitter of the resonate frequency generate by the tolerances of the components in the matching circuit will be visible for the user of Atyune.<\/p>\n

\"Touchstone<\/a>

Touchstone import to Atyune. The markers mark the lower GSM bands and the higher GSM bands plus UMTS band<\/p><\/div>\n

Everybody can play with to capacitors and inductors (up to four) in the matching circuit and see how the curve is moving in the Smith Chart.<\/p>\n

Further chapters tell about PCB layout, connecting layers together, shielding and a lot of further stuff that newbie’s do not know.<\/p>\n

What details I should add to minimise the trouble?<\/p>\n

Nevertheless, the readers will need a local engineering company to develop the matching circuit. I am looking for partners everywhere and my focus is on Germany, Austria, Switzerland and the Netherlands. I am looking for engineers that are able to measure the PCB with embedded antenna with a network analyzer optimising the matching circuit in the final enclosure of the IoT \/ M2M device.<\/p>\n
