Millimeter-wave base station for mobile broadband communication

Abstract

In this paper a millimeter-wave base station operating at 28GHz for mobile communication is introduced. This base station employs 64-elements antenna phased-array to enable adaptive beamforming required for mobile communication. The phased-array is constructed of sub arrays for optimal trade-off between performance and required coverage and beamforming capability. The phased array antenna is integrated with the transceivers on the same printed circuit board (PCB) using industry standard manufacturing process to minimize the cost and routing loss. The achieved link budget fulfills the requirements of the LOS and NLOS mobile communication in this band for distances in excess of lKm. The field measurements depict an end-to end EVM of better than -24dB for a 16QAM OFDM signal with 500MHz bandwidth (BW).

Wideband High Gain Antenna Subarray for 5g Applications

“…To overcome these challenges, highly directional antennas should be deployed. Antenna array of multiple elements focuses the radio energy into a narrow beam with high gain, which enhances the effective isotropic radiated power (EIRP) without increasing the transmitter power [19].…”

“…While microstrip antennas have been the subject of many intensive works for decades [20][21][22][23][24], they have been considered in some research efforts reported in the past few years on antenna design aspect of the newly emerging mmW wireless communications [19,[25][26][27][28][29][30][31][32]. Antennas in [19] and [25][26][27][28] are mainly designed to operate in one of the target frequency bands, as listed in Table 1.…”

“…Antennas in [19] and [25][26][27][28] are mainly designed to operate in one of the target frequency bands, as listed in Table 1. Nevertheless, wideband antenna arrays have received interests in 5G applications as they cover larger frequency bands and provide wider bandwidth and higher data rates.…”

Analysis and design of efficient passive components for the millimeter-wave and THz bands

“…However, the real present driver of the mm-wave technology are communications. Their role in our days society has put a lot of money on the table, triggering an explosion of work to satisfy new created service necessities [600]- [603], [608]- [609], [632]- [636]. The literature in the topic is tremendously vast, and the commercial race, phrenetic.…”

“…Third, there will be a cost reduction caused by the well-known effect of economies of scale. This will not only be provided by the massive development of all kind of radar types (SRR, MRR and LRR) as points [659], but the development to come from the telecommunications industry has much to say [600]- [603], [608]- [609], [632]- [636]. Regarding to this unavoidable relationship between both areas, a further reason can be added in this point.…”
