Resources:
- Trevor Marshall has created an excellent design for a 16 or 32 slot waveguide antenna
- Perth Wireless in Australia has a member who has also created a slotted waveguide antenna. It's a big success.
- Rob Clark from Perth Wireless has been making slotted waveguides using cheap downpipe, with extremely good results.
- Rob's downpipe antennas designs have also been implemented and documented at:

Take a look at my recent tutorial for BYTE.com describing antennas for WLAN deployment
The BiQuad antenna is a simple 2.4GHz WLAN antenna suitable for for 802.11 use. Details on how to construct this antenna, both as stand-alone and as a parabolic dish feed can be found at this link. The NEC simulation model, and sample output, can be found here.
