Dipole on a PCB - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.


 Post subject: Dipole on a PCB
Posted: Tue Mar 22, 2005 9:46 am 
I am new to the Antenna Design Field. I need to put a dipole antenna on my PCB. Frequency of Operation is 2.4GHz. I see that the length of the Antenna (half wave dipole) can be calculated from the wavelength (0.5* 300/2400 cm).
I am not sure about the balun, transmission line and feed point design. I have questions like which would be a good Transmission line- a coax or a twin lead conductor, what would be the length of the Transmission line, how to design a balun.
I would highly appreciate if someone can throw some light on it or direct me with any resource links, which would help my cause.
Thanks
Ram

Greetings Ram:

Many cellphones and other devices that use Bluetooth circuitry have the antennas printed right onto the PCBs. The vast majority of WLAN (802.11b/g/n) PCBs use printed antennas.

Your question is covered extensively in many books (1) and papers (2,3).

(2) http://www.ansoft.com/news/articles/02.06_MWJ.pdf

Hopefully, this will get you started.

Greetings Ram:

Good news! I just ran across an excellent application note by Freescale Semiconductor that is just what you are seeking.

hi, I am required to simulate a microstrip dipole antenna on Feko. I have found a reliable design but am having problems with feko. is there anyone out there who is able to help me.

thanks

cheers
Alvin
