Kent Britain WA5VJB has spent many hours working on PCB Antennas, both Log Periodic ( - ideal for multi-band dish feeds) and Patch designs. The original log periodic model shown below has performance peaks at the 2.3, 3.4 and 5.7GHz bands. In the picture it is shown in a rather neat and durable assembly by PA5DD - inside a sealed plastic container. This original design has been superceded by the newer LPY4 model.
UKuG no longer directly stock these. Sam Jewell G4DDK is the local contact for them. Sam's website has a special PCB Antenna page which covers these.

This unit was designed by David Wrigley (Scatterpoint-6) to be used with the level meter by Roger Blackwell (Scatterpoint-4 & 5). They can be used with great effect to measure and hence improve antenna performance - see Kent Britain WA5VJB article in Scatterpoint-1.
