“…Frequency allocation for one of the millimeter-wave 5G bands is at 28 GHz (27.5 -28.35 GHz) [35]. Notional architectures will include massive multiple input multiple output (MIMO) [14] and/or hybrid approaches, which will incorporate RF beamforming as discussed by [36] - [42].…”

This paper presents the design and development of two all flat panel phased array antennas (PAA) by using emerging 5G Silicon radio frequency integrated circuits (RFICs) at Ku-and Ka-bands. First, an X-/Ku-band wideband dual circular polarized Transmit (Tx)/Receive (Rx) phased array antenna with the capability of scanning (±45°) is presented. The frequency of operation is centered around 12.5 GHz within the X/Ku-Bands (3dB Axial Ratio (AR) bandwidth at broadside=32%). The array has 16-elements with a 4x4 lattice arrangement. This array utilizes a nested sequential rotation architecture, which enhances the axial ratio (AR) bandwidth. Secondly, a dual slant linear polarized (±45°) transmit and receive (T/R) phased array antenna, that operates in the Ka-Band and covers the millimeter-wave 5G band (27.5-28.35 GHz) is discussed. Beam scanning range is up to ±60° in both polarizations. In both cases, the array apertures have been integrated with an active beamforming networks (BFN) utilizing 5G silicon Tx/Rx beamformer RFIC chips. Measured and simulated performance results agree reasonably well in both cases. These arrays are scalable to larger size arrays to provide higher gain for applications like satellite communications (SATCOM) and 5G communications.

This article presents a MIMO compact antenna measuring 45×45×1.6 mm, on the FR4 substrate, proposed for Ka band and 5G communication applications. The proposed design is suitable to overcome the issues connected with massive MIMO. It has four-sigma-shaped radiating elements and a c-shaped ground plane with coplanar waveguide feeding. Its compact dimensions suit it for most existing communications systems. The aerial operates in the 21-30 GHz range, which covers Ka and 5G communication bands. The proposed antenna exhibits the average efficiency of more than 76% within its operating band and gives a minimum signal to noise plus interference ratio. The presented antenna covers several services, such as Ka band satellite downlink applications and future 5G communication applications.

“…This is because the received signal strength in HP/VP antenna systems has significant difference whereas the mean signal level in ±45 • polarized antenna systems is almost equal. During the past two decades, considerable attention has been paid to ±45 • dual-polarized antennas working in the low frequency bands for 2G/3G/4G base stations [7]- [10] and sub-6 GHz for 5G base stations [11]- [14]. Thanks to the advantages of wide bandwidth, high resolution, high gain, small size, etc., the millimeter-wave (mmWave) technology is considered as one of the potential solutions in future mobile communications for the purpose of delivering gigabits per second (Gb/s) data rate.…”

“…In [25], a mmWave ±45 • dual-polarized aperture antenna using low-temperature co-fired ceramic (LTCC) technology was proposed to achieve high gain, but this antenna has a very large size (≈ 2.4λ 0 × 2.4λ 0 ) which makes it not suitable for the antenna array design. In the low frequency bands lower than 6 GHz, generally speaking, most of the ±45 • dual-polarized antenna designs for base station applications are inspired by cross dipoles due to their wide bandwidth, high cross-polarization discrimination (XPD), and wide-angle scanning capability [7]- [14]. In [26], a differentially-fed cross slot antenna backed by a SIW cavity is designed to achieve high XPD and good port isolation.…”

This paper presents a novel dual slant polarized antenna for millimeter-wave (mmWave) base stations. Compared with the traditional slant polarized mmWave antennas, the proposed antenna offers the advantages of high cross-polarization discrimination (XPD), good aperture efficiency, simple structure, and low profile. The corner-fed substrate integrated waveguide (SIW) cavity is adopted to improve the port isolation and XPD of this slot-coupled antenna. Four corner-truncated patches connected by a thin cross strip are placed over the SIW cavity to increase the operation bandwidth. Then, a 2 × 8 antenna array is designed to exemplify the antenna element performance. To improve impedance matching, a shorted patch is introduced in designing the series feeding network and the power divider. The experimental results show that the 2-dB-down gain bandwidth of the proposed antenna array reaches 6.0% and the port isolation is better than 20 dB. The gain and XPD of the antenna array measure 16.7 dBi and 25 dB at the center frequency, respectively.
