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...

Antena Design for DSS(Direct Spread Spectrum) - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 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.

Hi friends

I am designing DSS (direct spread spectrum system).at this moment I have been designing a transmitter unit .I have a data signal with the frequency of 1 KHz and I have a PN code generator which has a frequency of 1MBPS ans i am EX-ORing (BPSK modultion) this 2 signals and now i want to transmit the modulated wave and i want to recieve the signal at receiver side .

My experiment is limied to the lab environment.

Any body could please let me know how can i achieve this ?how should i proceed for Antenna design for the above system.?

I am new to this stuff coud any one please give some insight of the issue?

Thanks a lot
