“…This consists usually of the strongest line-of-sight (LOS) component and few major reflections from different directions [56,57]. These properties together with the link blockage of the few propagation paths that may occur at various parts of the radio channel make mobile communications more challenging at mm-waves.…”

“…Channel measurements have been conducted by the industry and academia worldwide for the mmWave bands. The aim of these measurements is to understand and model the propagation characteristics of the design of 5‐G communication systems [4–16]. Channel characteristics, such as propagation losses (defined as path losses and shadowing), delay spread, angular spread, and penetration loss have been reported for use in urban micro (UMi), urban macro (UMa), indoor hot spot, wireless backhaul, device‐to‐device, and vehicle‐to‐vehicle applications [4, 17].…”

“…Studies have explored channel characteristics by conducting channel measurements; in such studies, angular channel parameters, such as angular spread, number of beams (clusters), and delay spread within a beam, have been reported for communication based on the single-beam operation [4,[7][8][9][10][19][20][21][22][23][24][25][26][27]. In these studies, the performance of the varied propagation conditions, such as the propagation path loss models for co-and cross-polarisation [28,29] and different propagation models with directional antennas [20][21][22][23][24][25][30][31][32][33][34][35][36][37][38][39][40][41], also have been investigated for communication based on the single-beam operation.…”

Owing to the global bandwidth shortage in frequency bands below 6 GHz, higher frequency bands such as millimetre‐wave bands will play integral roles in fifth‐generation (5‐G) communication systems. Beamforming is necessary for high‐frequency bands to maintain system coverage and increase system capacity through spatial division multiple access. Moreover, more than one beam might be used simultaneously to enhance signal quality and prevent blockages. Recent studies have investigated, focussed on power loss characteristics in multi‐beam operation, and compared the channel characteristics for single‐beam operation. To provide robust channel characteristics, knowledge of the multipath characteristics in multi‐beam operation is required in the design of 5‐G communication systems. To fill this gap such as the multipath dispersion characteristics of outdoor‐to‐outdoor propagation in delay and angular domains, the present study analysed outdoor data measured at 38 GHz and presented the propagation losses (path losses and shadowing), root‐mean‐square delay spread, and angular spread in multi‐beam operation. We believe that the dispersion statistics (delay and angular spreads) and propagation loss characteristics in multi‐beam operation would be useful in the development of 5‐G communication systems in high‐frequency bands.

This article presents the results of our research on the modeling of an HPT SiGe heterojunction phototransistor. Usually this HPTs type work for a single point of polarization in this work, we were interested in modeling the same HPT on different points of polarization. We will model the HPT to operate at both 2V and 3V, so that we can use the HPT at multiple bias points and reduce costs and allow the reuse of the HPT SiG heterojunction phototransistor on further studies. For a defined point of polarization we will optimize the operation of the HPT so that it flies with the dynamic measurements and we will not base on this HPT by modifying certain values and components so that the HTP works on the other points of polarization.
