FM microstrip antenna? - 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.

Posted: Tue Feb 07, 2006 9:58 am 
Hi,

Is there a program or online tool that I can use to help me design an FM antenna that I can etch on a PCboard? I was thinking of just soldering a piece of wire for my primitive FM receiver, but I wondered if it is possible to just implement a copper trace on a PCB. That way it will look nicer. :)

Is this possible? Thank you!

Hi,

It can be done, but, I am not sure you want to do that at FM frequencies. The size of the antenna would be very big and I dont think you would want to have such a big chunk of pcb lying around!!

Hi! I wanted to squeeze an antenna into a matchbox, so I thought if I etched a copper trace and zigzag it around a small board so I can get close to a quarter wavelength of say 100MHz, then that would do the job. But I guess not? Any tips of squeezing an antenna into a small box? I read that other small FM receivers use the actual headphone cables for the antenna, but I measured a headphone cable and it seems pretty short. Can't I just etch this same length into a board?

thanks!

Well, you could do that. If you have a zigzag line, or etch a multi turn loop, you could possibly achieve a small size. But, matching it would be the tricky part, coz the loop will be inductive, and the inductance will vary depending on the spacing between each turn of the loop. As another thought, why not wind the wire itself inside the box? That might be simpler.

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...
