In this letter, a novel 3D conformal annular slot antenna is proposed and patterned over a 3D printed cubic package with conductive surface in order to achieve a horizontally polarized omnidirectional radiation pattern in the azimuth plane. To verify the concept, a cubic antenna‐package at 2.4 GHz has been designed and fabricated for wireless sensor network applications application. The cube is printed by Objet 3D printer from Verogray material with thickness of 1.55 mm and covered with copper tape with slots being cut out of its surface at appropriate locations. The measurements are in good agreement with simulations. A maximum measured gain of 2.53 dBi at the azimuth plane and a bandwidth of 11% are achieved.
