Researchers have developed a new dual-polarized slotted bowtie antenna, optimized for operation in the sub-6 GHz frequency range. This design aims to enhance the efficiency and versatility of modern wireless communications, addressing the growing demand for multi-service systems in urban and rural environments. The antenna is capable of handling multiple frequency bands, making it suitable for a wide range of applications, from 5G networks to Internet of Things (IoT) systems.

The main novelty of this antenna lies in its bowtie configuration with strategically placed slots. These slots allow for the adjustment of the antenna's resonance characteristics and polarization, achieving optimal performance across different frequencies. Dual polarization is crucial for mitigating the effects of multi-path propagation and interference, resulting in increased link reliability and capacity in complex environments. The design has been validated through electromagnetic simulations, showing good agreement with performance requirements.

The antenna prototype features a compact size and an omnidirectional radiation pattern in the horizontal plane, facilitating its integration into various devices and structures. Experimental results confirm that the antenna operates effectively in the designated frequency bands, with good radiation efficiency and adequate isolation between polarization ports. This advancement is significant for the development of more robust and adaptable wireless communication infrastructures, essential for the large-scale deployment of emerging technologies. This type of antenna is expected to contribute to improving the quality of service and coverage in next-generation networks.
