The present invention relates to an antenna module which can minimize the occupying space in an electronic device, enhancing degrees of freedom to increase efficiency in space utilization, thereby accommodating miniaturization and multi-functionality of the electronic device, and an electronic device having the same. The antenna module includes a flexible substrate, an antenna element having a feeder part, a first fixing part, and a radiation part. The antenna module further includes a feeder line connected to the feeder part having a feeder pad, a first fixing pad connected to the first fixing part, and a pad coupling element. In the invention, signals are processed via interaction between the resonance of the current running through the feeder line to the radiation part and the resonance of the current coming into the pad coupling element.

An OFDM (orthogonal frequency division multiplexing) receiver is equalized by dividing each of a plurality of received OFDM symbols into a plurality of sub-symbols and outputting each of Fourier-converted signals corresponding to each of the sub-symbols, and estimating a channel response corresponding to each of the divided sub-symbols.
摘要:
In a resonant frequency tunable antenna, a body includes a dielectric substance and a magnetic substance. A first radiator is disposed on a first predetermined area of the body and has a feeding pin connected thereto. A second radiator is disposed on a second predetermined area of the body. Also, a switch is disposed on the body to be connected between the first and second radiators. In addition, a power supply pin is electrically connected to the switch and extends downward through the body.
