“…To combat this, directional antenna with high directivity gain can be adopted to obtain sufficient link budget. This can be accomplished using antenna arrays that provide advantages of interference mitigation and multipath suppression [1]. The challenge with directional antennas is beam alignment between the communication pair.…”

Abstract-Elevation-plane beam tilting is demonstrated for a printed dipole antenna operating over 57-64 GHz. This is achieved using a array of high refractive-index metamaterial (HRIM) unit cells. The unit cell comprises a modified H-shaped structure with stub loading to control the refractive index of the unit cell over a finite frequency range. Integration of the array in the H-plane of a dipole antenna is shown to deflect the main beam by with respect to the endfire direction over 57-64 GHz. In addition, the proposed technique provides 5 dB gain enhancement.

“…The MIMO system model is shown in Figure 1 The device 1 (DEV1) is equipped with a linear array of M transmit antennas, the device 2 (DEV2) has N receive antenna. Data transmission between the two devices involves the following: at the transmitter side, the signal after baseband processing is upconverted to RF band, then multiplied by transmitter code vector w. On the receiver side, then the received RF signal is down-converted to abaseband signal, and then multiplied by receiver code vector c; both weight vectors satisfy [7].…”

Abstract. Codebook design is a key point in beam-forming which is necessary for millimeter Wave (mmWave) communications to compensate its huge path loss. In our study, we demonstrate the benefits of the number of antenna elements for beamforming; we focus on the number of required beams to cover the whole circle with considering the available number of antenna elements. In addition to, we propose a new codebook structure based on unique phase states. Based on the Array Factor (AF) and Signalto-Noise Ratio (SNR), the proposed codebook is compared and evaluated with the uniform weighting codebook, circular array codebook, and IEEE802.15.3c standard codebook. The results show that the proposed codebook achieves SNR values and side-lobes cancel a bit better than IEEE802.15.3c, but higher peak and wider dynamic range of SNR and better array directivity compared with the uniform weighting and circular antenna codebooks. Thus, the proposed codebook is expected to improve signal quality and increases user throughput significantly.

“…In [3], improved spatial diversity is demonstrated with dual-beam Multiple Input Multiple Output (MIMO) compared with the classical MIMO, where a power gain of 1.6 dB is achieved at the 60 GHz band. Hosoya et al [4] and Ma et al [5] have shown that employing a dual-beam antenna at the transmitter and receiver improves the link quality where the link blockage is encountered due to multipath effect and mutual interference. Dual-beam antennas that radiate energy symmetrically at two different angles also find application in scanning and millimeter-wave identification (MMID) systems [6]- [8].…”

“…The measured reflection coefficient of the antenna is better than −10 dB over 57-64 GHz and the two radiation beams generated point at angles of 60°and 120°with respect to the end-fire direction (90°) with a maximum peak realized gain of 9 dBi. These properties make such an antenna suitable for improving the communications link of systems affected by multipath effect and mutual interference [4], [5], and in scanning and MMID applications [6]- [8].…”

This is achieved by artificially modifying the dielectric constant of the antenna substrate using arrays of metamaterial inclusions realized using stub-loaded H-shaped unit cells to provide a high index of refraction. The H-shaped inclusions are tilted with respect to the axis of the antenna and embedded in the direction of the end-fire radiation. The resulting dual-beam radiation in the E-plane has maxima at +60°and 120°with respect to the end-fire direction (90°), with a maximum peak gain of 9 dBi at 60 GHz.Index Terms-5G wireless networks, antenna, bow-tie antenna, broad beamwidth, dual-beam, millimeter-wave antennas.
