“…This paper continues the work of [13] by improving the mm-wave coverage with additional arrays of enhanced gain on each side of the phone and by implementing a diversity antenna to realize MIMO operations at the LTE bands. Whereas [13] was the first paper to incorporate mm-wave and LTE antennas in a shared volume, this paper is the first one to present a complete antenna system. The new simulations show that a sufficient performance level, which compares well to other designs, can be achieved with the same co-design method.…”

The coexistence of mm-wave and LTE antennas in modern handsets is yet an unsolved challenge in the phone industry and antenna research community. The different antenna types merged together in a shared volume easily hinder each other's performance. This paper extends the work published recently, showing how high-gain mm-wave antennas at 28 GHz can be incorporated in the same volume with LTE MIMO antennas. The results show that with small compromises a decent performance can be achieved at both mm-wave and LTE bands.

“…The mmWave 5G technology is one of the optimal choices to achieve higher data rates as it uses higher carrier frequencies. 28 GHz frequency band is of high interest for deployment of mmWave 5G antennas [2]. In addition to this, Multiple-Input Multiple-Output (MIMO) technique is a conventional method to enhance data rate.…”

“…Due to availability of limited space in mobile phones, integrating 4G LTE and mmWave 5G antenna architectures on the same module is challenging. Designs reported in [2,4] have implemented the co-design architecture of 4G LTE and mmWave 5G antennas, but they have large physical footprint which is not attributed to orthogonal pattern diversity for using smartphone in portrait as well as landscape mode. In addition to this, gain at mmWave frequencies in the reported work is low.…”

Co-design of corner bent Multiple-Input Multiple-Output (MIMO) antennas catering to 4G LTE and mmWave 5G applications is proposed. The 4G LTE MIMO antenna module consists of two element microstrip-fed slot antennas operating from 1.7 to 3 GHz with fractional bandwidth of 55%, which covers LTE1900, LTE2300, and LTE2500 bands. For mmWave 5G MIMO antenna module, two element Vivaldi antennas with wideband operating from 25 to 38 GHz and fractional bandwidth of 41% are proposed. The mmWave 5G microstrip fed Vivaldi MIMO antennas exhibit orthogonal pattern diversity at 28 GHz with 1-dB gain bandwidth of 28%. The single element corner bent co-designed antenna is compact having dimensions of 14 × 51 × 0.254 mm 3. The 4G LTE and mmWave 5G antennas are electrically close to each other by 0.01λ at 1.7 GHz for minimal physical footprint. Co-designed 4G LTE and mmWave MIMO antennas are integrated inside a typical mobile case. Simulated and measured results are presented.

Beamforming is the central concept that can make millimetre-wave (mmWave) a viable solution by solving challenges of link-budget, cost, power, form factor, complexity, regulatory constraint and so on. Before deployment of mmWave beamforming solution for 5G, and possibly beyond, several fundamental questions need to be answered. Some of them include hardware constraints, performance matrices, realistic propagation channel models including impairments due to obstacles such as body, blockages due to casings, phase noise, a model for Spatial-temporal variations in channels, and advanced MIMO techniques for multi-carrier and multi-user communications. The site constraints and massive non-line-of-sight transmission within the urban environment are severely questioning the conventional terrestrial low power node deployments that used to work well at low operational frequencies (sub-6 GHz). In addition to this, in beamforming technology using massive antenna arrays, the coordination of the users and beams at the transmitter and receiver end within a large network are very challenging. In this study, we comprehensively investigate some of the most prominent and best practice solutions that attempted to answer these challenging questions.
