Narrative:
A possible near miss occurred in the uncontrolled traffic pattern at ak-chin rgnl (A39). My aircraft just completed a touch and go off runway 04 to depart the pattern. I did not hear any traffic entering left downwind so I announced my left crosswind turn to depart the airport traffic pattern at 400-500 feet AGL and well past the departure end of the runway. After doing my 45 degree right turn to depart the pattern; I noticed another aircraft ahead entering an extended down wind leg. I maintained my lower altitude of about 500 ft below the published traffic pattern to avoid any conflict. The other aircraft passed overhead at about 400-500 feet and finally announced his position above me. I was a low wing aircraft and the downwind aircraft was a high wing cessna so both aircraft maintained sight until passing. No conflict but a learning event for us both. See and avoid and more radio calls if possible when two aircraft are converging.contributing factors for me was a large flock of bugs hitting my right side of the windscreen hindering my clear vision to my right and ahead. This made it harder for an earlier detection of an aircraft approaching from that angle. I also did not hear any downwind calls from the aircraft ahead to alert me of any possible traffic. If I knew an aircraft was ahead or entering downwind I would fly further upwind before turning for my cross wind departure from the airport and pass will behind any extended downwind aircraft.
