A novel miniature all-polarization Γ antenna array for demanding 5G and Internet of Things (IoT) applications is proposed. The antenna is designed to be able to perform Direction of Arrival (DoA) and Beamforming keeping antenna's footprint as minimal as possible to fit in or wrapped around any IoT device. It is a non-uniform square array comprised of novel right corner dipoles which are mirror placed to additionally allow all polarization property. These properties are inherited from its approximate equivalence to a cross-dipole antenna with additional features and flexibility. An analytical mathematical formulation is presented resulting to a closed form for the Γdipole as well as the 4 dipoles array. Numerical simulations proved the antenna performance and verified that all of its features are approximately retained even when it is curved. The antenna is prototyped in both an improvised wire dipole (planar or curved) ad as printed on an FR-4 substrate. The measured results confirmed the analytical and numerical ones regarding the antenna all-polarization, beamforming and direction of arrival features.
