Abstract:
This paper describes the design of a helical antenna at GPS upper L band frequency. Helical antennas are widely used in airborne and space borne applications to receive GNSS signals. One major concern in reception of GNSS signals is their susceptibility to jamming signals. To address this problem a novel antenna design is proposed in this paper. The proposed design provides lower side lobe levels than conventional helical antennas, without compromising efficiency of the antenna. The lower side lobe levels are the key feature in making the antenna less susceptible to jamming signals. Moreover,

Abstract:
Helical antenna is one of the antennas which are very popular among amateurs satellite. In the X-band frequency, circularly polarized antenna is necessary, because it can overcome the effects of anomalous propagation, ground reflection, and rotational dynamic effects that occur in many satellites. These antennas have a large enough gain, that can reach 15 dB and has a directional radiation pattern with a bandwidth ratio of 1.78: 1 and is almost close to the broadcast antenna (≥ 2). The purpose of this research was to design, create prototypes, and analyze performance of X-band helical antenna

Abstract:
The 5G cellular network aims to address bandwidth needs due to the large number of subscribers worldwide. However, higher-bandwidth antennas are needed to integrate into the design. Helical antennas offer design simplicity, gain, and wider bandwidth, but their radiation pattern narrows bandwidth as diameter and turn increase. This paper aims to develop and evaluate the performance of helical antennas at different dimensions and turns for 4G and 5G network frequency applications. The study used MATLAB 2021a to design and simulate helical antennas with various turns. Parameters like width, spaci

Abstract:
Here we propose the use of twist and glide symmetries to increase the equivalent refractive index in a helical guiding structure. Twist- and glide-symmetrical distributions are created with corrugations placed at both sides of a helical strip. Combined twist-and glide-symmetrical helical unit cells are studied in terms of their constituent parameters. The increase of the propagation constant is mainly controlled by the length of the corrugations. In our proposed helix antenna, twist and glide symmetry cells are used to reduce significantly the operational frequency compared with conventional h

Abstract:
We present a design of a high-gain quad array of nonuniform helical antennas. The design is obtained by optimization of a 3-D numerical model of four nonuniform helical antennas placed above a ground plane, including a model of a feeding network, utilizing the method of moments with higher-order basis functions. The gain of one optimal nonuniform helical antenna can be about 2.5 dB higher than the gain of a uniform helical antenna of the same axial length. Creating a 2×2 array further increases the gain up to about 6 dB. The resulting quad array fits into a box whose dimensions are 2.5×3.3×3.3

A unique property of spherical and hemispherical helical antennas is that they provide very broad half-power beamwdiths and circular polarization over a narrow bandwidth. In this thesis, new designs for hemispherical helical antennas are introduced that provide significant improvement in bandwidth, while maintaining the directivity and half-power beamwidth of the basic design. In the basic design, a simple wire of circular cross section is wound on the surface of a hemisphere, whereas in the proposed new designs a metallic strip forms the radiating element.

This dissertation details the development of a novel reduced size axial mode helical antenna called the Stub Loaded Helix (SLH). The SLH achieves a significant reduction in helix size, both diameter and length, compared to the conventional axial mode helix antenna with only small compromises in performance. The SLH achieves this entirely through the use of a unique geometry. The performance characteristics of the SLH are explored through the use of computer simulations using NEC (Numerical Electromagnetics Code) to study the effects of design parameter variations.

Cylindrical helix and planar spiral antennas produce circularly polarised (CP) radiation over a wide bandwidth. Unfortunately this circular polarisation is not maintained in off- axis directions. This research investigates the Spherical Helical Antenna (SHA) which is essentially a helix which has been tapered to give it a spherical envelope. The SHA is shown to produce good quality CP over both a wide bandwidth and a wide beamwidth. Custom FORTRAN code has been written which implements the Method of Moments (MoM) technique in order to model the antenna. Curved segments are used and these are s

Abstract:
The genetic algorithm (GA) is used to design helical antennas that provide a significantly larger bandwidth than conventional helices with the same size. Over the bandwidth of operation, the GA-optimized helix offers considerably smaller axial-ratio and slightly higher gain than the conventional helix. Also, the input resistance remains relatively constant over the bandwidth. On the other hand, for nearly the same bandwidth and gain, the GA-optimized helix offers a size reduction of 2:1 relative to the conventional helix. The optimization is achieved by allowing the genetic algorithm to contro
