Chart Or Publication; Human Factors; Airspace Structure; Procedure
Aircraft X [was] cleared for an RNAV GPS Runway 32 approach into MIC and [I] instructed [the] aircraft to cross a fix at 3;000 ft. I checked [the] chart twice on this new approach and was not comfortable with 3;000 ft. and climbed the aircraft to 3;500 ft. until [I] passed the obstruction of some antennas. Upon further review; the aircraft should have crossed WAKUD at 3;400 ft. for [the] MVA of 3;500 ft. by the chart. I have reviewed the chart and SOP's to become familiar with this new approach as well as obstructions in airspace for currency. [I] also reviewed IFR chart legends and procedures in general to make sure [I was] reading them correctly.
A TRACON Controller reported clearing an aircraft for a new approach and issued a crossing restriction below the MVA.
