“…The contributors of this article stated a miniature printed CP antenna for DBS use. These are the unique features of the prototypes: The antenna has been significantly reduced in size, achieving a reduction of 21.03 % . The antenna provides decent gain and a very impressive bandwidth of 0.8 GHz. It provides complete coverage of the DBS service band in terms of CP bandwidth at 100 % . The antenna offers more than 85 % aperture 51,52 and above 95 % radiation efficiencies, 53–57 respectively. Additionally, it provides a correction factor (CF) of 44.27 dB/m, 60–64 suggesting that it has low impact of EMI/EMC. …”

SummaryThis article presents a highly compact printed radiator for direct broadcast satellite (DBS) systems that exhibits good gain and left‐handed circular polarization. The inferred pattern is accomplished by etching two isosceles triangles, one from each of the four corners of a square. From the center of the newly acquired structure, a circular geometric design is made up of 16 isosceles‐scaled triangles has been etched. This arrangement induces resonance in the antenna, aligning it with the desired frequency. The proposed antenna is designed using PCB laminated Rogger 5880 material and simulated in a CST EM simulator. The antenna under consideration exhibits a significant size reduction, achieving a miniaturization ratio of 21.03%. The LHCP antenna resonated at 12.61 GHz and offered a decent LHCP gain of 7.95 dBic. It gives 0.56 GHz CP bandwidth, which covers the DBS service band entirely. It also provides 96.43% radiation efficiency and 44.27 dB/m correction factor, respectively. All the measured findings of the prototype agree with its simulated one.

Abstract-Shelkunoff circle synthesis techniques are only effective for equispaced antenna arrays. These techniques are based on reorganizing the zeros on the Shelkunoff circle. We propose a technique based on locating complex-direction zeros to synthesize arbitrary on-board antenna arrays. It is based on the analytical continuation of Green's functions and on a new representation of the complex plane (analogous to the Shelkunoff circle).
