“…The helix radius will affect the resonant frequency of the helix antenna. By changing the radius of the helix, a better match with the design frequency can be achieved [ 25 ]. The best electrical performance can also be obtained by changing the geometry of the antenna, such as using a dual-arm hemispherical helical antenna [ 26 ].…”

The electrical performance of the feed array is degraded because of the position deviation of the array elements caused by manufacturing and processing, which cannot meet the high performance feeding requirements of large feed arrays. In this paper, a radiation field model of the helical antenna array considering the position deviation of array elements is proposed to investigate the influence law of position deviation on the electrical performance of the feed array. With the established model, the rectangular planar array and the circular array of the helical antenna with a radiating cup are discussed and the relationship between electrical performance index and position deviation is established by numerical analysis and curve fitting method. The research results show that the position deviation of the antenna array elements will lead to the rise of the sidelobe level, the deviation of the beam pointing, and the increase of the return loss. The valuable simulation results provided by this work can be used in antenna engineering, guiding antenna designers to set optimal parameters when fabricating antennae.

A helix antenna serves as an electromagnetic emitter that transmits signals in the shape of a coiled thread. It possesses two primary operational modes: normal and axial. In the axial mode, radiation peaks along the helix's axis, creating a near-circular concentration of electromagnetic waves. This paper delves into the intricacies of designing a spiral antenna optimized for operation at a 3 GHz reverberative frequency. It exhibits indirect polarization and is ideally suited for wireless communications, facilitating the transmission and reception of VHF waves, especially for ionospheric propagation. The versatility of this antenna extends to various applications, including radio astronomy, space telemetry, satellites, and space-based communication systems. The proposed antenna design showcases a directional radiation pattern with a notable gain of 13.8 dB. Future research will explore its adaptability for deployment in aquatic environments, expanding its utility in scenarios that demand reliable wireless connectivity beneath the surface. This innovation holds great promise for enhancing communication capabilities across a range of fields and environments.

Many design optimization problems have problems that seek fast, efficient and reliable based solutions. In such cases, artificial intelligence-based modeling is used to solve costly and complex problems. This study is based on the modeling of a multiband helical antenna using the Latin hypercube sampling (LHS) method using a reduced data enhanced multilayer perceptron (eMLP). The proposed helical antenna is dual-band and has resonance frequencies of 2.4 GHz and 2.75 GHz. The enhanced structure of the artificial neural network (ANN) was tested using 4 different training algorithms and a maximum of 10 different MLP architectures to determine the most suitable model in a simple and quick way. Then, performance comparison with other ANN networks was made to confirm the success of the model. Considering the high cost of antenna simulations, it is clear that the proposed model will save a lot of time. In addition, thanks to the selected sampling model, a wide range of modeling can be done with minimum data. When the target and prediction data are compared, it is seen that these data overlap to a large extent. As a result of the study, it was seen that the ANN modeling and the 125 samples used, were as accurate as an electromagnetic (EM) simulator for other input parameters in a wide range selected.
