Circling for 34 At Chicago Executive. Following a Citation Jet & Challenger Jet. Was circling for 34. Got a lot of wake turbulence behind the jets on the circling approach. Reported it to the Tower [who] suggested [I] do a 360 but because of the altitude of Class B decided not to do a 360 but wanted to stay out of the wake turbulence so could not descend below the Class Bravo. Due to the long base to final to maintain separation and avoid the jet wake [I] encroached the Class B airspace. Was aware of the fact [and] exited as soon as safely possible and landed at PWK.
Single Engine Turboprop pilot reported an airspace incursion resulted from his efforts to avoid wake turbulence on approach to PWK in trail of two corporate jet aircraft.
