Abstract | The authors proposed a folded aperture-coupled patch antenna (ACPA) on a flexible printed circuit (FPC) with vertically polarised end-fire radiation, suitable for fifth-generation millimetre-wave massive multi-input–multi-output (MIMO) systems. For low-cost implementation, antenna elements were fabricated on a single polyimide substrate. The fabricated FPC was first folded to implement a three-layer ACPA, and then the feed line was bent 90° to achieve end-fire radiation. Measurement of five antenna samples demonstrates that the resonance frequency lies between 27.7 and 28.3 GHz. Each antenna sample has the bandwidth (∣S 11∣ < −10 dB) >1.2 GHz. The measured antenna gain is 2.74 dBi at 28.1 GHz, and the difference between co- and cross-polarised radiation intensities is >15 dB in all directions of interest. To improve the impedance bandwidth and the gain further, they increased the distance between the patch and the aperture of the proposed antenna by folding the fabricated FPC multiple times without an additional layer. Experimental results confirm the bandwidth of 2.64 GHz (26.27–28.91 GHz) and the gain of 3.80 dBi at 28 GHz. Additionally, the 1 × 8-folded APCA array is simulated to verify the feasibility for a practical application of multi-beam massive MIMO technology. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
