can you design ?

sorry for double biquad i mean

thanks Can this design be used for biquad?

Hi admin what are these ? is copper ? just support or ...

Hi admin do you here ?

thanks admin Please give me the sizes of this design as well Or is it the same size as before?

oh realy thanks

thanks In our area, only PCBs with a thickness of 1.6 and a thickness of 0.35 can be found Is it possible to design for this type of material?

Thanks, my friend I want this antenna for fpv I will definitely make your design and test it on the UAV I bought the antenna you see in the picture I haven't tested it myself yet, but apparently it works great My friends tested and reached a range of 30 km with a power of 1 watt I do not need this amount Coverage is more important to me For example, with two diversion receivers and 90 degree coverage and 10 dbi gain for 10 km distance I have a few questions to make this antenna 1. If I use fr4 with a thickness greater than 0.8, like 1.6 and add to the height will the antenna have the same performance? Or do I want to use a steel plate instead of its FR4? 2- Is the thickness of copper 0.25? Is there a problem for me to use 0.35? (Finding a 0.25 board is really hard) 3- Is it possible to design based on multiples of lambda? Because the network may be busy, I have to switch to Frequency 5280 Thank you in the end pcb antenna 5.2ghz.IGS

Hi admin I know the date of this post is very old, but if possible, do the design for the 5200 frequency as well i want to make it thank you

hi admin what is dimensions of panel antenna with 4biquad(16.5dBi) ??

Hi can you please share model coto detail and do you have this model ?

ok if you like in end simulate twine crosshair antenna and report dimension for 13db antenna

blue wall is dielectric and just for cover in paperbox and not important in design please see link and design like pic http://fpv.no/vbulletin/showthread.php/10891-DIY-Pepperbox-antenne

no just hubby

yes I think simulate pepperbox is not hard for you...!!

please use dielectric characteristics of crosshair that you simulate

now can you please simulate papperbox (not crosshair) antenna in CTS

position thanks have you any datasheet about this or CTS ? another question : which antenna is better than for beamwith in same gain (13db) 1- dual-biquad 2- papperbox

i want know distance between two crosshair antenna or any data that is new in papperbox antenna after merge two crosshair antenna

yes i know that papperbox antenna composed two crosshair antenna

i haven't any link for papperbox antenna but crosshair antenna is sharing

I think distance beetwen two cross hair antenna is important for design cross hair antenna see this https://fpvlab.com/forums/showthread.php?3626-Crosshair-10-dbic-Circularly-polarized-antenna-tutorial! and https://docs.google.com/spreadsheet/ccc?key=0AuQ2aX6fBQhQdDlWUi1IY0J3NUMwd1pmU2Z0b0UxMXc#gid=0

yes can you simulate this antenna ?
