Abstract. We study the influence of both the electromagnetic source singularity and electromagnetic cavity resonances on the current distribution of a dipole antenna within a rectangular cavity. These two types of electromagnetic singularities are triggered by the radius of the dipole antenna and the quality factor of the enclosing cavity, respectively. The key element of our investigation is a novel representation of the electromagnetic Green’s function for a lossy rectangular cavity. It allows to directly obtain the current distribution on the antenna by means of the method of moments. As a result it is recognized that a dominating source singularity, i.e., a small antenna radius, can inhibit resonating effects, even if a cavity resonance is excited and the quality factor of the cavity is high.

AbstractIn this paper, a cross dipole antenna is proposed, designed, and developed for satellite communication applications. The design incorporates an alternative feeding mechanism of the coaxial/probe feeding technique with balun. The primary objective of this paper is to develop the high gain antenna with an array configuration for satellite communication. The performance parameters of an antenna such as return loss, radiation pattern, gain and directivity are investigated for cross dipole antenna and 1 × 2, 1 × 4 array configurations. It operates for Ku band (12–18 GHz) and produces a high gain with low return loss. The proposed antenna has five useful bands and exhibits a peak directive gain of 13.21 dBi at 12.4 GHz with a bandwidth of 0.89 GHz. Additional bands are also offering a gain of 11.23 dBi with a bandwidth of 0.849 GHz at 10.6 GHz, 6.59 dBi with a bandwidth of 0.6 GHz at 11.5 GHz, 12.13 dBi with a bandwidth of 1.37 GHz at 14.2 GHz and 10.47 dBi with a bandwidth of 1.3 GHz at 15.8 GHz. The cross dipole antenna is analyzed for 1 × 2, 1 × 4 array configuration in order to improve the overall gain. The proposed antenna is fabricated on FR4 substrate with a dielectric constant of 4.4 and loss tangent (tan δ) of 0.007 with the thickness of 1.6 mm. The size of the proposed antenna is 72 × 84 mm. The proposed antenna meets the requirements of an antenna which is operating at Ku band; hence, it is found to be suitable for real time applications.
