While executing an ILS approach I experienced windshear on short final. I noticed a decrease in airspeed; loss of altitude and received a low altitude alert from the Tower Controller. I increased power and leveled off to stop the descent and increase my airspeed. Looking straight down I was able to determine I was over the runway but not in a position to land. I initiated the missed approach and started a climb as per the missed approach clearance. I may have descended below the decision altitude for the approach. While being careful not to fixate on the airspeed indicator I should have noticed the loss in airspeed sooner; this would have prevented any loss of altitude. I have also raised my personal minimums by 300 feet over what is specified in the terminal procedures.
SR22 pilot experiences windshear during an ILS approach resulting in a loss of airspeed; descent below the glideslope and possible descent below minimums. ATC issues a low altitude alert and a missed approach is initiated after first leveling off at low altitude with the runway not clearly visible.
