A compact low-profile phased array antenna unit with unidirectional hemispherical beam-coverage for 5G mm-wave applications is proposed in this paper. A four-subarray configuration is used for the proposed structure to achieve unidirectional hemispherical coverage in the boresight direction normal to the substrate. An artificial magnetic conductor (AMC)-backed slot antenna array with ... https://parisnaturalfoodes.shop/product-category/super-toddlers-probiotic/
