Abstract: An antenna module using a planar inverted-F antenna is disclosed. The antenna module according to the present invention comprises: a panel having a shape of a rectangular flat plate, each side of which has a length less than or equal to 1/2 of a wavelength (λ) of a preset center frequency; and at least one planar inverted-F antenna in which one of four diagonal lines is disposed, wherein each of the four diagonal lines has an independent ground plane having a length of 0.3λ or less and is oriented in a direction from the center of the panel to the edge of the panel. Therefore, up to four planar inverted-F antennas each having an independent ground plane are disposed in the antenna module having a square shape, each side of which has a length less than or equal to 0.5λ, in diagonal directions from a center of a square, thereby maintaining a 90-degree angle one another. Hence, a large number of planar inverted-F antennas can be disposed in a limited area, while minimizing mutual interference. In addition, as a plurality of antenna modules, in which at least one planar inverted-F antenna is disposed, is combined and arranged in various forms, a maximum number of the planar inverted-F antennas can be disposed in a limited space, without mutual interference.

Abstract: A beamforming device for a communication system using a multi-antenna is disclosed. The present invention can implement a beamforming device combing digital and analog methods by including a plurality of phase controllers corresponding to each of the plurality of D/A converters or A/D converters instead of having a plurality of D/A converters or A/D converters less than the number of antennae. Therefore, the plurality of D/A converters or A/D converts are made to correspond to multiple data streams, and the size and manufacturing costs can be reduced by decreasing the number of D/A converters or A/D converters.

Abstract: A planar inverted-F shaped antenna is disclosed. The present invention includes: an antenna body surface in which each of the more than one planar inverted-F shaped antennae has a length and a width corresponding to a predetermined center frequency and transmits and receives electromagnetic wave; a ground surface having a width less than the width of the antenna body surface; a short-circuit unit which has an upper end connected to one side of the antenna body surface and a lower end connected to one side of the ground surface; and a feed line separated from the short-circuit unit at a distance which corresponds to predetermined impedance for performing impedance matching and transmitting a signal by being connected between the antenna body and the ground surface. Therefore, the size of a planar inverted-F shaped antenna having a ground surface is able to be reduced by maintaining the radiation characteristics of the antenna while having the same or smaller ground surface than the antenna body.
