Modeling and Synthesis of Compressed High-Order Mode Dipole Antennas


With the increasing popularity of 5G, 6G, and other next-generation wireless systems, there has been a surge in demand for enhanced antenna gain performance and beamforming capabilities of antenna radiation patterns across diverse application scenarios. Currently, antenna arrays represent the primary method for achieving high gains and beamforming, yet their feed networks are inherently complex and introduce additional losses. To address this challenge, we have introduced the concept of compressed high-order mode dipoles. Initially, we introduced the compression coefficient K, revised the equation for calculating the far-zone electric field of the dipoles, and put forward the notion of compressed high-order modes. Subsequently, we individually compressed the high-order mode currents, formulated the theory of non-uniform compression, and developed a high-gain dipole and a wide-beam dipole through non-uniform compression of the third-order mode. Building upon this foundation, we proposed the continuous source current equation to offer theoretical insights for designing non-uniformly compressed high-order mode dipoles, leading to the creation of a high-gain and low side-lobe fifth-order mode dipole. Ultimately, we integrated artificial neural networks with the non-uniform compression theory to facilitate efficient and rapid beamforming for high-order mode dipole antennas.
