Abstract
Et antenneelement for en gruppeantenne omfatter en transmisjonslinje 1 ført gjennom et jordplan 3, forbundet ved et eksitasjonspunkt 8 til et plant, ledende, spiralformet eksiteringselement 6 anordnet på et dielektrisk substrat 4 på oversiden av og parallelt med jordplanet 3. Avstanden mellom eksiteringselementet 6 og jordplanet 3 er større enn én åttendedel av den lengste bølgelengde for de signaler antennen er innrettet for å operere med, og foretrukket mellom 0.25 og 0.50 ganger bølgelengden. Banelengden for den elektriske lederen som utgjør eksiteringselementet er større enn nevnte bølgelengde, og helst mellom 10 og 100 ganger bølgelengden. Dette medfører at eksiteringselementet opererer som en lekkbølgestruktur, slik at antenneelementet blir ikke-resonant. Videre beskrives en gruppeantenne med et antall slike antenneelementer anordnet i en kvadratisk matriseoppstilling, der det benyttes et felles jordplan 3 og et felles substrat 4. En dielektrisk linse 7 er anordnet på oversiden av antenneelementet eller gruppeantennen.An antenna element for a group antenna comprises a transmission line 1 passed through a ground plane 3, connected at an excitation point 8 to a flat conductive spiral excitation element 6 arranged on a dielectric substrate 4 on the upper side of and parallel to the ground plane 3. The distance between the excitation element 6 and the ground plane 3 is greater than one-eighth of the longest wavelength for the signals the antenna is designed to operate with, and preferably between 0.25 and 0.50 times the wavelength. The path length of the electrical conductor constituting the excitation element is greater than said wavelength, and preferably between 10 and 100 times the wavelength. This causes the excitation element to operate as a leakage wave structure, so that the antenna element becomes non-resonant. Also described is a group antenna having a plurality of such antenna elements arranged in a square array, using a common ground plane 3 and a common substrate 4. A dielectric lens 7 is provided on the upper side of the antenna element or group antenna.
