Thank you for the video, It actually really precise and helpful for me to understand.
but I have a questions, as you mentioned Linear antenna has longer range than circular and its good if you can be able to predict the tag orientation, could you specify it in more detail about your meaning of tag orientation?
tags needs to line up in same format? or if in the box some RFID tags are attached bottom but next box attached on the left linear antenna still can read it?

sir what should be the minimum distance between the reader and antenna

Thanks for answer. I saw some video where man can move few degrees and signal was ok with linear. So on plane whitch is almost in same position with no acrobatics you will get better range with linear ? Can you say haw big difference in altitude can be ? Or angle

can i ask, when i mesured the rssi used landmark system with circular polarization patch antenna, when i moved the antenna from (the right to the left ) and from (the the left side to the right side)of my landmark system the results are diffrent ? why? can be related to the left and the right circular polarization of the antenna ?

Can i ask, which antenna would be the ideal for a marathon? a race...

Will it be possible If I would create an antenna that would surround my whole door from, will it be able to detect the rfid that would pass in the door which is in the middle of the antenna?

can i augment the gain of microstrip patxh antenna 867MHz(rfid)? if the answer is yes, than how?

[janprejzek]

Can i ask, why is circular anthennas with helical used for "long" range instead of more range with linear anthenas (as you say) ?
Thank you
