ARRAY ANTENNA OF MOBILE TERMINAL AND IMPLEMENTING METHOD THEREOF

摘要

Disclosed are an array antenna of a mobile terminal and implementing method thereof. The array antenna includes: a mobile terminal ground plane, located at the same side as a dielectric material substrate and configured to act as a radiation main body to radiate antenna energy coupled by multiple couples of coupling elements; multiple couples of coupling elements corresponding to multiple antennas, each of which is fixed at the two ends of the mobile terminal ground plane, and configured to excite the waveguide mode of the mobile terminal ground plane to radiate coupled antenna energy via the feed point of the respective feed line of each coupling element therein; a matching circuitry, located at the other side of the dielectric material substrate and connected with a feed point located at the other side of the dielectric material substrate, and configured to implement the impedance matching of a microstrip feed line for each coupling element. The present invention can reduce the correlation among antenna units, and ensure that the array antenna has better all-directional radiation characteristic, and is convenient for the design of terminal device minimization.
