Multiple-band monopole coupling antenna

摘要

A multiple-band monopole coupling antenna includes a dielectric board, a low frequency antenna and a high frequency antenna. The low frequency antenna and the high frequency antenna are located on the front of the dielectric board. The length of the low frequency antenna equals to the half length of the low frequency waves and can receive and transmit two low frequency waves and a high frequency wave. The length of the high frequency antenna equals to the quarter length of the high frequency waves. The high frequency antenna is adjacent to the low frequency antenna and couples with the low frequency antenna while the low frequency antenna is receiving or transmitting signal. Thus, the high frequency antenna can receive and transmit three high frequency waves. The multiple-band monopole coupling antenna can receive and transmit all frequency bands, which are used in the mobile communication.
