A repeater is provided. The repeater includes: a hybrid butler matrix configured to perform beamforming of a MIMO antenna for transmitting and receiving a base station signal; a hybrid butler matrix configured to perform beamforming of a MIMO antenna for transmitting and receiving a user terminal signal; and a signal processor configured to amplify a signal to be transmitted and received through the hybrid butler matrix. Accordingly, it is easy to manufacture a repeater, heat emission and power consumption can be reduced, and a cost of production can be reduced.

Wireless repeater

Disclosed is an electronic device, which includes a housing, a display that is exposed through a first region of a front surface of the housing, a first antenna radiator that is positioned within the housing, and a communication circuit that is positioned within the housing. The display includes a pixel layer including pixels and a conductive sheet layer under the pixel layer. The conductive sheet layer includes a first conductive region, a second conductive region, and a slit interposed between the first conductive region and the second conductive region. The first antenna radiator is electrically connected with the first conductive region of the conductive sheet layer. The communication circuit receives a signal in a specified frequency band through the first antenna radiator and the first conductive region. Above this, various embodiments figured out through the specification are possible.

Electronic device including antenna using structure of display panel

A microstrip patch antenna includes a via-hole pad including via-holes, a patch disposed on the via-hole pad, a feeding via-hole disposed at a side of the patch through the patch and the via-hole pad, and a shorting via-hole disposed at a side of the patch, and configured to connect the patch and a ground unit.

Microstrip patch antenna in cavity-backed structure including via-hole

A patch antenna having a single patch fed with multiple signals is provided. The patch antenna includes: a first patch; a first feeder and a second feeder which are connected to the first patch; and a second patch which is parallel to the first patch. Accordingly, since multiple signals can be fed into a single patch, a MIMO antenna can be embodied by using a patch antenna which has high isolation between feeders without increasing its size.
