Conception et réalisation d’une antenne plate pour la réception satellite

Abstract : Despite the development of terrestrial links, satellite communication is remaining an interesting mean of information transmission. Broadcasting, pay-TV operators, video, data and broadband Internet services are provided by satellites in a trustworthy way. An important component for the satellite communication, other than the satellite itself, is the receiving antennas deployed all over the world with a huge number. The most popular one is the parabola but this structure does not meet any longer the new aesthetics and the additional functional requirements. For this purpose, motivated researchers worldwide are working on presenting new discreet and self-steering receivers. Indeed, new structures that allow automatic beam steering are beginning to merge into the market but with relatively high prices. We aim with the present work to design a flat antenna array with electronically beam scanning at an affordable price. Therefore, an alternative broadband receiving antenna is designed and implemented for TV channels reception in Ku-band. It consists of an antenna array of 256 radiating elements. The radiating element of an original shape is designed using a methodological approach based on printed antenna theory and simulations. A bandwidth of over 2 GHz (10.7 – 12.7 GHz) is obtained from this printed element with a footprint of less than the wavelength. With a suitable array configuration, a directivity of about 30 dBi is achieved, good enough for geostationary satellite signal reception.
