Narrative:

After spending the day performing maintenance on the communication antenna I taxied my plane out to the active runway at the airport where it's based to verify the radio issues I'd been having for the last 2 months had been fixed in flight before returning to service. The mission was traffic pattern work. That day there was little other airport traffic. I flew my first circuit without retracting the gear as intended to verify operation gradually and safely. My second circuit; the gear was retracted on upwind; a normal pattern was flown; and the gear retracted again on downwind abeam the runway numbers with 3 green lights confirming. On the third circuit I forgot to re-extend the gear and was across the runway threshold before noticing the landing gear buzzer going off. Before having time to react to the problem the nose began to vibrate from the propeller striking the runway and I could hear the scraping sound accompanied by a sight picture uncharacteristically low for a normal landing that made me realize my error.I quickly pulled the mixture all the way out to kill the engine and shut off the master switch while the belly of the plane slid down the middle of the runway. After coming to a stop shortly after I announced my gear-up landing on the active runway not realizing that the communication antenna was scraped off the bottom of the fuselage by that point. Then I shut off the fuel selector and magnetos and egressed the plane to head towards the FBO. The aircraft was put back on its wheels and towed to a hangar by airport management. The radios performed acceptably throughout the flight; but multiple occasions of extended downtime caused by mechanical needs over the last several months of ownership made staying proficient difficult. Had I been more fastidious about the landing checklist and not have gotten rusty from the setbacks; I believe this incident could have been avoided.
