Abstract
Modern communication systems at millimeter-wave (mmwave) frequencies or above rely on phased-arrays with possible beam steering capability. Antenna arrays with narrow beam, high gain, and good circular-polarized (CP) characteristics over a wide frequency band are always preferred. In this paper, a design with a 64-element magneto-electric (ME) dipole array is presented based on standard PCB fabrication technology. The array antenna achieves a wide impedance bandwidth of 76.8% (18.94-42.54 GHz) and an overlapping axial ratio bandwidth of 69.9% (19.24-39.93 GHz). The CP array achieves a peak gain of 22-24 dBic, a radiation efficiency of 70%-85% across the band, and a 3-dB beamwidth of 18°. The planar configuration, combined with wideband CP performance and the ease of fabrication, makes the proposed design highly suitable for the design to be integrated with satellite communication (SatCom) and mm-wave front-end subsystems.
A compact, wide band circularly polarized antenna array for mm wave frequency bands has been presented in this article. The proposed design exhibits very simple structure with of chamfered circular patch utilized with meta surface and sequential rotation feeding mechanism to enhance the impedance and axial ratio band...
A single-port differential-fed 12-element linear antenna array is developed for wideband millimeter-wave (mmWave) communication systems, with the 28-GHz band as the primary target providing wide frequency bandwidth (FBW), high gain, low side lobe level (SLL), and highly symmetric radiation characteristics. A wideband s...

An ultra-thin flexible antenna array based on dualband, dual-polarized antenna elements is presented in this paper. In ultra-thin millimeter-wave antennas, maintaining high isolation between orthogonal polarizations across two frequency bands is challenging due to strong coupling through the patch structure and limited...

A low-profile tri-band millimeter-wave (mmWave) dielectric patch (DP) antenna (DPA) is proposed for fifth-generation (5G) and beyond wireless communication systems. Multiband operation is achieved by exciting the resonant TM11, TM31, and TM51 modes at approximately 22, 30, and 36 GHz, respectively. Crucially, these ope...
