Antenna at 433 MHz - 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 antenna on my PCB. Frequency of Operation is 433MHz. I see that the length of the Antenna (quarter wave dipole) can be calculated from the wavelength (0.25* 300/433 cm).

I would highly appreciate if someone can throw some light on it or direct me with any resource links, which would help my cause.

you can visit below mentioned page and see different low power application antenna fabricated in PCB, of course i tried the same for 916 MHz and it worked fine.

    Kirt Blattenberger,


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...
