Abstract
In next-generation mobile networks, hundreds of diverse devices aim to be interconnected, posing huge challenges in capacity, coverage, efficiency, reliability, and connectivity. These and other challenges are addressed at Radio Frequency (RF) parts such as several radiating unit antennas, with very fine beamforming capabilities along with the requirements of high gains and minimized size. This work presents an 8×8 Aperture Coupled Microstrip Patch Antenna (AC-MPA) in the form of a planar array modeled for the 28GHz frequency band with high gain and compact size, making it suitable for 5G networks. The antenna is designed using a substrate with overall dimensions of 74.6×85.648×0.107mm3 and relative permittivity of ε0 = 4.3.
Highlights
Moving towards 5G means increased data rate needs in order to meet the requirements of high quality applications such as video streaming, endless connectivity, and maximum capacity and coverage with reduced cost [1,2,3]
Antenna arrays in generation networks for mobile communication at higher frequency spectra, such as the mm-Wave band, have received attention to meet and support the growing higher data rates with greater throughput and improved performance [4,5,6]
The proposed antenna is a planar array with 64 elements formed with single elements of dimensions 9.4×10.75×0.107mm3
Summary
Moving towards 5G means increased data rate needs in order to meet the requirements of high quality applications such as video streaming, endless connectivity, and maximum capacity and coverage with reduced cost [1,2,3]. A number of array designs for 5G broadband communication have been proposed [11,12,13] Almost all these antennas occupy large space in mobile phone devices operating at very few 5G bands. The need of enhanced communication is essential due to the advancement and exponential growth of new technologies such as the massive Internet of Things (IoT), which are less power demanding and low-cost. These technologies consist of connections among hundreds of small size sensors, with specific application such as agriculture, smart cities, smart home, etc. The proposed spectrum for 5G by 3GPP (3rd Generation Partnership Project) consists of two bands, one below 6GHz ( known as the sub-six band) and one above 6GHz, typically from 26GHz to 40GHz ( known as millimeter wave) [15,16]
