An antenna module for a cellular phone which is capable of minimizing the effect of electromagnetic radiation of the cellular phone on the human body and enhancing the quality of speech of the cellular phone. The antenna module comprises two helix antennas installed in the cellular phone transversally apart from each other, and a power supply unit connected to the helix antennas for applying two power signals with the same power level and opposite phases respectively to the helix antennas. This antenna module is able to radiate a minimized amount of electromagnetic waves in the longitudinal direction of the cellular phone, or toward either the top or rear part of the cellular phone, and an increased amount of electromagnetic waves in the transversal direction of the cellular phone, respectively, thereby minimizing electromagnetic radiation to the human body while at the same time enhancing the quality of speech of the cellular phone.
An antenna module for a cellular phone, comprising:
An antenna module for a cellular phone having two helix antennas wherein said helix antennas are installed in the cellular phone transversally apart from each other, have opposite helical directions such that they have opposite phases while remaining matched with each other and are connected to power supply means to receive the same amount of power therefrom.
