Dipole on a PCB - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

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).

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.

"Compact Integrated Antennas"

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

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
