“…This paper investigates a multimode circular waveguide corrugated horn antenna using the 3D printing process to drastically reduce its weight and cost compared with the aluminium prototype of the same. The simulation results of this waveguide horn were earlier reported in [7,16,17] but it is the first time, we have built and tested this horn using the both 3D printing process and precision milling based aluminium prototype. The paper is organised as follows.…”

“…The authors in [4][5][6] presented a feed horn but focused on reducing cross-polarisation in the far-field pattern of the linear polarised reflector antenna. In [7], the design of the feed horn presents a scanned radiation pattern which is used for limited beam steering. The benefits of using a multimode waveguide horn are that it generates multiple phase centres similar to the reported in [2,3] or scanned radiation patterns over a limited range by controlling the amplitude and phase of the modes in the proper ratio.…”

Three‐dimensional (3D) printing technology based antenna structures have many promising applications. In this study, a triple mode circular waveguide horn antenna with corrugated chokes is presented. In this antenna configuration, three individual modes consisting of TE11, TM01, and TE21 are generated in a single structure. The horn antenna prototypes used precision milling and 3D printing process for the aluminium and 3D printed horn antenna prototypes, respectively. The aluminium prototype is used as a reference antenna for comparing the 3D printed horn prototype. For the 3D printed antenna, Polycarbonate ‐ Acrylonitrile Butadiene Styrene (PC‐ABS) material is used and later coated with conductive silver ink. Simulation and aluminium based prototype antennas achieve a common bandwidth of 7.45–8.00 GHz for all the three modes. However for the 3D printed antenna prototype, the achieved bandwidth is from 7.40 to 7.89 GHz. The aluminium and 3D printed horn prototypes were also tested for radiation pattern quality. While aluminium‐based prototype agrees closely with the simulation results, the 3D printed horn shows a reduced gain, higher cross‐polarisation levels while keeping the pattern beamwidths similar to the simulated and aluminium‐based horn prototypes.

“…A novel triple-mode feedhorn designed earlier in [6] is reanalysed using FEKO. The feedhorn that excites the TE 11 , TM 01 , and TE 21 , modes is analysed to understand its impedance and radiation performance as well as radiation performance when the modes are combined.…”

“…Due to this reason and also that a detailed phase center study was shown in [2], hence is not included here. Additional triple-mode feedhorn performance results were discussed in [6], therefore are omitted here for the sake of brevity.…”

“…Consequently, reflector antenna impedance matching and radiation performance are investigated for both the symmetric and offset reflectors and a comparison is made when only two modes from the feedhorn are excited at a time. The triple-mode feedhorn operates in the frequency range of 7.47 GHz to 8 GHz and generates beam scanning performance by exciting the modes in proper amplitude and phase combinations which was preliminarily discussed in [6]. Some initial investigations on the reflector antenna performance with this feedhorn were presented in [7].…”

Parabolic symmetric and offset reflector antennas adaptively illuminated using a novel triple-mode feedhorn (TE 11 + TM 01 + TE 21 ) with different mode combinations and impedance and radiation performances are presented. The combination of the radiating modes in a feedhorn with proper amplitude and fixed phase values helps in electronically pointing the main beam of the radiating patterns such as that obtained in a beam-steering antenna with limited beam-scan range. This type of radiation performance virtually creates a displaced phase center location for the feedhorn, which, consequently, adaptively illuminates the reflector antenna surface. Impedance-matching bandwidths are preserved for both reflector antennas similar to the case of feedhorn alone. The copolarization gain and peak cross-polarization levels are far better with the offset reflector antenna than the symmetric reflector antenna. Such reflector antennas find applications in ground moving target indicator (GMTI) and space based radars. The investigation results are solely computed using FEKO full-wave analysis tool.

With the development of highly integrated technology, a large number of satellites have been launched into synchronous orbit, saturating the number of satellites in these orbits. As a result, there has been a substantial increase in demand for near-Earth orbit satellites. However, due to their proximity to Earth, the location of these satellites rapidly drifts in free space. To maintain the received and transmitted signals within range, the ground antenna must track the satellites immediately. Therefore, near-Earth orbit satellite tracking has become a key technology in satellite communication research. In order to further improvement, we propose a new type of electronic beam squinting (EBS) tracking feed. In this paper, we will conduct both theoretical and experimental analyses of this EBS feed.
