Mini-Beam Geometry Basics - There is a natural progression of the geometry of the "mini-beams" deriving from the basic yagi, which in itself owes a lot to the common dipole. By Dick Stevens, N1RCT

Biquad Antenna Construction - This page details the construction of a biquad antenna. The biquad antenna is easy to build, and provides a reliable 11dBi gain, with a fairly wide beamwidth.

BiQuad 802.11b Antenna - BiQuad 802.11b Antenna 11dBi, wide band by Trevor Marshall

Dish 802.11 Wireless Networking Antenna - This antenna modification is for the IEEE 802.11b networking protocol that operates at 2.4 GHz. It can be scaled easily to the 5 GHz frequency used by IEEE 802.11a by simply scaling the dimensions on the feed can and the excitation antenna to 2.4/5 = 48% of the dimensions shown above.

DirectionalBiQuad - Seattle Wireless - A biquad is a fairly powerful antenna which is relatively easy to construct, with impressive performance for their size. A link greater than 5 miles can be made with a pair of these as a stand-alone antenna and a Prism2 100mW card, provided you keep coax short, and your line-of-sight is clear.
