When creating a project (or project template), you need to set labels on the required monitors. I put everything by default.monitor.jpg

Hi Admin! All antennas are good, but someone is interested in the wi-fi range, someone is mobile. I have not seen any 1700-3800 antennas. in the minimum size and good radiation pattern. I am more interested in the variant of mobile frequencies, I simulated it. the antenna is not quite easy to configure and the developers hid it. It took a little work to get to the calculated results. Make a model for 2400-6000, you know what I'm talking about. Regarding the manufacture of TDJ from wire - yes, you can. on Lan, it was miscalculated in various ways. Initially, TDJ 2327 was intended for the ranges 2300-2700, the second version with a parasitic element (ring) began to overlap 1700-2700. It is very interesting to measure the resulting structure. What happened in the end?

 

ps Judging by the photo, the person who made the antenna does not understand anything about this (

Harry, I thought it was better to do a separate topic with this antenna, don't you think it's better that way...???!!!

,,,the frequency band of the antenna is 700-4000 MHz

,,, if you want I'll delete it ... !!!
