“…5G (5th generation) mobile networks using millimeter-wave (mm-Wave) spectrum provide large bandwidths and multi-gigabit communication services [1]. Due to the complexity of the 5G communication system and different propagation characteristics compared to lower frequencies, researchers need a low-cost but high-gain and steerable antenna system with moderate performance to overcome the new challenges [2]. Antennas with beam-steering capability can significantly improve the reliability and performance of communication link through an improved signal to noise ratio (SNR) at the receiver without increasing the transmit power [3][4][5].…”

In this paper, a dual-polarized four-port 2 × 2 series fed antenna array operating at 28 GHz with beam-switching capability is proposed. The antenna array uses a simple passive beamforming network to switch the main beam. The presented antenna design is suitable for 5G user equipment and high data rates applications by which it has a compact size with low cost and complexity. The size of the antenna is 37.2 × 37.2 mm2 including the ground plane, and it produces 10 different switched beams by using only two simple 3 dB/90∘ couplers which create the required amplitudes and phase excitations for the antenna elements. A one-port simple feeding mechanism including Peregrine PE42525 SPDT switch modules and a power divider is used to generate and measure the 10 switched beams. The antenna design is implemented on a two-layer 0.203 mm thick low-loss (tanδ = 0.0027) Rogers 4003C substrate, and it has a measured 10 dB impedance bandwidth of 4 GHz (14.3%, from 26 GHz to 30 GHz) for all ports. Measured peak isolation between any dual-polarized ports of the antenna is better than 30 dB. The antenna has an average measured realized gain of 8.9 dBi and around 10 dB side lobe level (SLL) for all beams. The antenna has 3-dB coverage of 80∘ to 90∘ in 2D space and it has a maximum of ±26∘ beam-steering angle. The antenna is designed and simulated using Ansys HFSS and fabricated using regular PCB processing.

“…in order to overcome high propagation attenuation rate in mmWave bands. Due to the complexity of 5G communication system and different propagation characteristics compared to lower frequencies, researchers need a low cost but high-gain and steerable antenna system prototype with moderate performance in order to study new challenges [2]. This paper addresses this requirement by proposing a microstrip line (ML) structure on RO4003C™ substrate based on an economical Printed Circuit Board (PCB) process in order to reduce prototyping cost.…”

This paper presents a low-cost, beam-steerable 4 × 10 antenna array system operating at 60 GHz. The proposed antenna system is fed by a 4×10 Butler Matrix network designed using microstrip line (ML) structure. Chebyshev tapered microstrip antenna arrays with 10 series-fed elements are connected to four output ports of the feed network. Four steerable beams with maximum 16.5 dBi system gain and 1GHz bandwidth(BW) satisfy the requirements of millimeter wave propagation study and handset application for 5G communication.
