S- 88 mm 35 mm 44 mm -F (74 mm 13 mm 16 mm) 2.25 GHz 25.6 db, 0.26 db, 49.4 db.. Abstract In this aer, we roose a comact antenna hat to erform RF comatibility testing efficiently between the launch vehicle and ground stations. The roosed structure imlements a small size and low loss using the conductive shield instead of the conventional RF absorber. The S-band antenna hat, which is fabricated for an inverted-f onboard antenna with the size of 74 mm 13 mm 16 mm, has the small enclosure of 88 mm 35 mm 44 mm, the return loss of 25.6 db, the insertion loss of 0.26 db, and the leakage loss of 49.4 db at the center frequency of 2.25 GHz. The simulated and measured results show a good agreement. Key words: Antenna Hat, Antenna Test Couler, Launch Vehicle, RF Comatibility Testing, Telemetry. 서론,, (skin) RF /.,, /. 1 RF (comatibility).
