thanks for your replay ......
I have doubted because the data sheet shows its working in 30-90% RH and it give output 2970mv at 90%RH .........??? and I calculated the value
%RH= adc_val*90/(2970mV/4.8mV)
but i didn't get the correct value ....so pls clear my doubt
hai all
I need to know how to convert 10bit adc value for a humidity sensor SY-HS-220 ......pls give any formula for converting that adc value to relative humidity value........
HAI ALL,
I have a doubt about substrate height of the patch antenna...
If we use substrate material as FR4(dielectric constant=4.4) ..and while calculating the antenna equations how can i take the "Height", if the pcb and the ground plane is separated with air gap ?? Is the substrate...
hai..
Now I am designing a microstrip patch antenna with coaxial feeding technique....I am using CST microwave studio for simulation purpose..and I am new to that software ...I need to know how to fix a coaxial line in the antenna for feeding purpose by using CST Microwave studio..???
Thanks for your replay CG021079 .....
I also need more help about single feed corner truncated circular polarized patch antenna.....and how to improve the gain and bandwidth of such antennas......
Regards key_
hai all ......
I decided to make a patch antenna and I need to design it in cst microwave studio...I am new to that software ....so how can i do the simulation..?
hai all ..
I saw a construction of a simple patch antenna.....the feed point of the antenna is located with a perfect impedance match position of the patch ....
I need to know how to select a perfect position for feeding the signal in patch in order to match the impedance of the coax line(50...
Thanks for the pdf .....
I also need to know about circular polarized -square, edge truncated-patch antennas............and designing of a stacked structure of the same?
Regards key_
hai all,
I decided to design a printed dipole antenna for gsm application.So I need to know how to calculate the dimensions of a printed dipole antenna (Length,line width and gap between the lines)......
Hi all,
I need to get a suitable amplifier Ic used for rfid reader..
I am going to use AS3991 Ic as rfid reader....so I need to know which is most better external power amplifier IC
