Abstract

La présente invention concerne une antenne de téléphone cellulaire à faible valeur de DAS, ladite antenne de téléphone cellulaire comprenant un boîtier ayant une carte mère disposée en son sein, et la carte mère comprenant un point d'alimentation d'antenne principale; l'antenne principale est une antenne PIFA ayant deux contacts. Les contacts sont courbés et étendus vers le bas pour être connectés au point d'alimentation de l'antenne principale; une pièce à EBG de cristal électromagnétique plane est disposée au-dessus de la masse métallique de la carte mère et en dessous de l'antenne principale, la connexion de ladite pièce à EBG de cristal électromagnétique plane avec la masse métallique proche étant mise sous tension ou hors tension pour modifier la direction de rayonnement de l'antenne principale. Ainsi, il est possible de commander le pointage du faisceau de l'antenne de téléphone cellulaire, ce qui permet de commander de manière efficace la propagation d'ondes électromagnétiques, et ainsi de réduire le rayonnement de l'antenne de téléphone cellulaire vers les corps humains de sorte que la valeur de DAS de l'antenne de téléphone cellulaire soit comprise dans une plage spécifiée.
