Abstract：
 Multiaerial system is composed of two pieces of plane type monopole antenna and two pieces of plane type inversion F antenna. The inversion F antenna is perpendicular to the monopole antenna. Vertical distance between two pieces of feed line is 15mm. It is 4mm of distance between the feed point of inversion F antenna and central line at Z-axis direction of dielectric plate, where two pieces of monopole antenna and two pieces of plane type inversion F antenna are located at. It is 26mm of distance between upper edge of inversion F antenna and upper edge of T type ground plane. Position of plane type inversion F antenna on the said dielectric plate is located above plane type monopole antenna vertically. Radiating elements in two pieces of plane type inversion F antenna are near to ends of two sides of dielectric plate or folded to T type ground plane. Advantages are: small size, little relativity between antennae, large gain and according with requirement of mobile communication.
