A multilayer patch antenna with high gain when operating in the automatic dependent surveillance‐broadcast (ADS‐B) band is designed for cubesat application. The antenna comprising a slotted‐patch radiator, a defected ground, and dual reflectors has a compact size of 80 × 80 × 8.76 mm 3 for suitably placing into a cubesat. By properly embedding slots into the patch elements of the antenna, directional radiation pattern with gain of 6.98 dBi at 1.090 GHz and an impedance bandwidth of 17 MHz (1.087‐1.104 GHz) can be achieved for the ADS‐B signal receiving. Validation is done by fabrication and measurement of the antenna prototype and shows good agreement between simulation and measurement.
