Abstract

An antenna assembly includes a circuit board, and one antenna device disposed on one side of the circuit board, for receiving and transmitting signals laterally, and another antenna device disposed on the other side of the circuit board, for receiving and transmitting signals vertically, to prevent the signal receiving and transmitting operations of the antenna devices from being interfered with each other. The antenna devices each includes two antenna members for receiving and transmitting signals toward different directions relative to each other, and each having two or more antenna segments for receiving and transmitting signals of different frequencies.

Claims

1. An antenna assembly comprising:

a circuit board including a first side and a second side,

a first antenna device disposed on said first side of said circuit board, for receiving and transmitting signals laterally, said first antenna device including two antenna members disposed in mirror symmetric relative to each other for receiving and transmitting signals toward different directions relative to each other, said antenna members of said first antenna device being disposed side by side relative to each other and each including a first antenna segment and a second antenna segment for receiving and transmitting signals of different frequencies and an intermediate antenna segment disposed between said first and said second antenna segments, said intermediate antenna segments of said antenna members of said first antenna device each including an extension extended outwardly therefrom for coupling to an electric cable, said first and said second antenna segments of each of said antenna members of said first antenna device being disposed up and down relative to each other, and

a second antenna device disposed on said second side of said circuit board, for receiving and transmitting signals vertically, to prevent signal receiving and transmitting operations of said first and said second antenna devices from being interfered with each other, said second antenna device including two antenna members disposed in mirror symmetric relative to each other for receiving and transmitting signals toward different directions relative to each other, said antenna members of said second antenna device being disposed up and down relative to each other and each including a first antenna segment and a second antenna segment for receiving and transmitting signals of different frequencies and a base antenna segment having said first and said second antenna segments extended therefrom, said first and said second antenna segments of each of said antenna members of said second antenna device being disposed side by side relative to each other, and said base antenna segments of said antenna members of said second antenna device each including one end for coupling to an electric cable.
