By simultaneously transmitting multiple different waveform signals, a multiple-input multiple-output (MIMO) radar possesses higher degrees of freedom and potential in many aspects compared to a traditional phased-array radar. The spatial–temporal c

A dual-functionality printed dipole array antenna is proposed in this study with a fan-beam property. An integrated balun structure cooperation with the dipole arms creates a resonance in the X-band for the antenna. Adding Single-Ring Split-Ring Reso

In this paper, two different architectures based on completely and sectionally clustered arrays are proposed to improve the array patterns. In the wholly clustered arrays, all elements of the ordinary array are divided into multiple unequal ascending

Abstract In this paper, two H‐plane horn antennae are designed using groove and ridge gap waveguide (GGW and RGW) techniques. In the proposed structures, the gap waveguide is partially filled with a dielectric to control the amplitude and phase dis

The occurrence of cross-beam interference in the received signal is one of the main problems that limit the possibilities of massive multiple-input–multiple-output technology (massive-MIMO) in fifth-generation (5G) systems. Thus, the evaluation of

In this paper, we propose a multi-beam integrated radar and communication scheme using phased-array antenna, in which the same LFM-BPSK integrated waveform is used for both the radar and the communication beams. In the integrated beam design, the rad
