SummaryThis paper introduces an innovative four‐element Ultra‐wideband (UWB) MIMO structure featuring an integrated global system for mobile (GSM) antenna with the ability to achieve dual and triple band‐notch capabilities. The antenna's distinctiveness is achieved through the utilization of four directional meandered line shaping decoupling structures (MLSDS), an orthogonal arrangement, and multi‐slot techniques. The incorporation of orthogonal separation alongside four directional MLSDS significantly reduces the mutual interference between radiating elements. By placing MLSDS on both sides of the substrate, effective coverage of the GSM band is achieved. The development of the MIMO structure unfolds through four distinct phases. The initial stage lacks MLSDS, while the second stage incorporates MLSDS. The third and fourth stages respectively introduce MLSDS with dual and triple notch characteristics. The presence of MLSDS enhances the antenna's impedance bandwidth (IBW). The intended notches are tailored to address interference from bands like Band n41, WLAN, and X‐band. Furthermore, the proposed antenna has undergone simulation, measurement, and comparative analysis with existing models, focusing on diversity performance metrics. The results reveal its exceptional diversity performance, positioning it as a potential choice for creating a portable UWB‐MIMO system.

“…In the LTE base station antenna technology, application in the automotive and base station, several reported designs [29][30][31][32] introduced perpendicular elements to achieve pattern/polarization diversity. Still, this is quite challenging in low-profile antennas for handheld devices due to limited space.…”

This paper presents a low-profile, stub-loaded multi-slot antenna that operates across 850 MHz to 4500 MHz. Remarkably, the new design meets the call of covering wideband frequencies used by many 4G and 5G New Radio bands from UHF to C bands. The antenna consists of two wide slots on the ground plane. Each slot comprises a straight segment connected to a larger circular slot. A novel microstrip feed line loaded with dual circular stubs excites the multi-slot antenna. The slots and feed lines are printed on each side of the dielectric substrate. This novel design offers pattern diversion capacity based on port excitation. Two prototypes were fabricated and tested to verify multiple simulation results including bandwidth, isolation, and group delays. A close consistency of measured and simulated results validates the design. Concurrently, good isolation between ports and nearly omnidirectional gain patterns are observed over the band. Further, the form factor of the proposed antenna makes it a suitable solution for modern 4G and 5G handheld devices.

“…In contrast to the above literature, in [16] we exploited the eigenmode decomposition technique to achieve polarization diversity without the use of matching networks allowing reduction implementation complexity and enabling greater operating bandwidth. To generalize this work, in [17] we have proposed an antenna based on a new eigenmode design procedure which can achieve both polarization and pattern diversity without the use of matching networks. In this paper we comprehensively validate the antenna concept sketched out briefly in [17] by providing a theoretical background, analysis, and measurements.…”

In this paper we propose an antenna design procedure based on the eigenmode decomposition technique which avoids the use of the external matching networks that are typically required at the input ports of the mode decomposition network (MDN). We illustrate the technique by examining the properties of a circularly symmetrical 4-port antenna configuration which can achieve four orthogonal radiation patterns or eigenpatterns and that allows both polarization and pattern diversity. We then use the proposed theory to design an actual antenna structure with eigenmodes operating around 2.6 GHz and whose eigenpatterns are directed in one hemisphere. The antenna and an example MDN are manufactured and tested showing that the four eigenmodes can simultaneously operate in 9.5 % of bandwidth (RL > 10 dB) with a worst case total radiation efficiency of 72 %, correlation coefficient of 0.04, and port coupling of-24 dB. Finally, we use the measured results to assess the antenna in a Multiple-Input-Multiple-Output (MIMO) communication system and demonstrate its beam-tilting capability.
