Integration Of Antennas With Sun-Tracking Solar Panels, Adam Narbudowicz
Articles
A low-cost solution for antennas integrated into solar cells, allowing their implementation in solar tracking installations is proposed. The proposed passive device autonomously adjusts the phase shift of a two-element array proportional to the panel rotation. Consequently, the main beam is steered to compensate for panel rotation and maintain a radio link. The proposed device operates for a rotation of ±45° with an amplitude variation of ≤0.4 dB at 2.51 GHz.

In order to achieve lightweight yet low cost antennas for use in a geostationary space environment, the GeReLEO-SMART project develops a substrate-based, multilayer antenna structure which can replace traditional horn antennas as feeds for reflector antennas. To verify a design, an example mission is developed, consisting of a 2×2 patch antenna array with an integrated stripline bandpass filter. The operation frequency is 25.935 GHz. This multilayer antenna will be tested on board of the German technology demonstration mission “Heinrich-Hertz” (H2SAT). The design passed all tests for space qualification without decrease in performance.

—A novel reconfigurable antenna capable of rotating a bidirectional pattern by 360◦ in azimuth is proposed. The antenna has two ports, no aperture switching components, and offers a more compact solution than an array. It provides a reconfigurable pattern in the band 2.525–2.595 GHz and a fixed omnidirectional pattern from 2.235 to 2.725 GHz. The measured gains for four investigated configurations are between 2.1 and 3.1 dBi with total efficiencies between 80% and 89%. The antenna is intended to operate with software defined radio [digital beamforming or multiple-input–multiple-output (MIMO)], where the potential of pattern generation using the dual-port antenna can …
