Conception d'une antenne réceptrice omnidirectionnelle et multipolarisations dédiée aux récepteurs portables de radiomessagerie

Abstract : The receivers of radio-broadcasting in general and espacially those of paging receiver are equipped with essential element which is called the antenna. This element is defended as device of coupling between radiated wave in free space and the transmission line which leads to the receiver. In principle, such compact portable receivers use whether inductive antenna particulary sensitive at magnetic field, or capacitive antenna sensitive at electric field. The technological progress of such receivers results for the most part from conception and development of compact antenna less cumbersome characterised by a sensitivity less or equal to 35 dBuV/m. The essential objective of this work is to show the technical and industrial feasibility of a new type hybrid omnidirectionnel and multipolarisation antenna intends to paging receivers operational in frequency band II (87.5 - 108 MHz). Two ideas are essential to achieve a such antenna : the first one consists in associating two antennas which were developed at TDF-C2R. It concerns one antenna with miniaturised magnetic core and loop in short circuit. The formed so a resultant antenna composed of two inductive antennas perpendicular. Both of then sensitive at magnetic field. The second consists of electronic system indispensable is the extraction of the signal caring the information. So, the system suggested presents a particular advantage which is based on its simplicity them on its cost and its reliability. The role of a such system is to ensure the total of a such system is to ensure the total of both signals shifted of 90°
