After that Wolfgang Schrader (CEO of antrax Datentechnik) checked four of their cellular antennas and forwarded the result to me. The SP1 files I loaded to Atyune and made the return loss visible. On top I started with playing with automatic generating of matching circuits by Atyune.<br \/>\nOn 2th. of October I got a daily training on <a href=\"http:\/\/www.linear.com\/designtools\/software\/\">LT Spice<\/a>. A simulation module for a switched mode DC\/DC power supply on <a href=\"http:\/\/www.linear.com\/product\/LT8614\">LT8614<\/a> I already have on my hard disk. The simulation includes a GSM module with its 2 Ampere peaks as well. I got the simulation module by Marco Abbondanzieri (FAE at Linear Technology).<\/p>\n<p>My next task will be to integrate the graphs out of the LT Spice simulation to the IoT M2M Cookbook and upload it the simulation module to the download zone. This module you can use to learn and go ahead changing of parameters or replacing the DC\/DC power supply with LT8614 to another one.<\/p>\n<p><strong>Coming soon (already in process)<\/strong><\/p>\n<ul>\n<li>Export of <a href=\"http:\/\/en.wikipedia.org\/wiki\/Touchstone_file\">Touchtone (SP1) files<\/a> generated with MinVNY Tiny and import to <a href=\"http:\/\/qucs.sourceforge.net\/\">Qucs (Quite Universal Circuit Simulator)<\/a>.

Hopefully every reader of the IoT M2M Cookbook will able to calibrate and to check their antennas within a few minutes. The test report of the four antennas unearth the true. One out of the four antennas is not resonate in the promises frequency range. It is impossible to tune. However, the SP1 file of this painful antenna is like the other three tested antennas ready for download. You can download it and try to optimise it yourself.<\/p>\n<p><strong>Planned<\/strong><\/p>\n<ul>\n<li>Power supply simulation by <a href=\"http:\/\/www.linear.com\/designtools\/software\/\">LT Spice<\/a><\/li>\n<li>Power supply simulation by <a href=\"http:\/\/qucs.sourceforge.net\/\">Qucs<\/a><\/li>\n<\/ul>\n<p><strong>Wish list<\/strong><\/p>\n<p>Just tell me your wishes.
