A first radiating electrode 5 and second radiating electrode 6 are formed on an upper face 2c of a dielectric base 2 of a surface-mounted antenna 1, and a rectifying circuit 7 is formed on a side face 2b where radiating electrodes 5 and 6 are not formed. This facilitates configuration of a desired rectifying circuit 7 appropriate for the surface-mounted antenna 1, and rectification of the surface-mounted antenna 1 is facilitated. Also, since the rectifying circuit 7 is formed on the side face 2b of the dielectric base 2, effects of the rectifying circuit 7 on the first radiating electrode 5 and second radiating electrode 6 on the upper face 2c can be reduced. Accordingly, high gain and increased bandwidth of the surface-mounted antenna can be obtained.
L'invention concerne une antenne à montage en surface (1) qui comprend des premières et secondes électrodes rayonnantes (5, 6) formées sur la surface supérieure (2c) d'une base diélectrique (2), et un circuit d'adaptation (7) formé sur un côté (2b). Cette structure facilite l'établissement d'un circuit d'adaptation (7) approprié à l'antenne considérée (1), ce qui assure l'adaptation d'impédance souhaitée pour ladite antenne (1). En outre, on peut réduire l'influence du circuit d'adaptation (7) sur les première et seconde électrodes rayonnantes (5, 6) à la surface supérieure (2c), car le circuit d'adaptation (7) est placé sur le côté (2b) de la base diélectrique (2). On peut ainsi augmenter le gain et la largeur de bande de l'antenne (1).
