An antenna design solution is provided. A metal frame and a PCB ground layer of an electronic device are used to form a slot. Through symmetric feeding and anti-symmetric feeding, the slot can be excited to generate two slot antenna patterns: a CM slot antenna pattern and a DM slot antenna pattern. In addition, the two slot antenna patterns share a same slot antenna radiator.

A simple multi-directional, multi-port array antenna structure is disclosed that can be used for a variety of applications, including but not limited to direction finding (DF) and beam-forming applications in receive and transmit modes, respectively. The disclosed antenna structure offers unique functionalities in both receive and transmit modes. For DF applications in the receive mode, the back-end of the antenna structure features a power sensing mechanism to monitor the power received at all ports. In the transmit mode, the disclosed antenna structure is used for beamforming applications by providing individual port excitation and using antenna arrays.

In an embodiment, an electronic device may include a first cover covering an upper portion of a main body and containing a first antenna module disposed on a lateral portion thereof, a spacer member disposed over the first cover, and a second cover disposed over the spacer member. The first and second covers may be spaced apart from each other at a predetermined distance due to the spacer member, and a separation space between the first and second covers may be configured to operate as a second antenna module. It is therefore possible to guarantee high-efficiency wireless performance having iso-directionality without compromising the design of the electronic device. Other embodiments are also possible.
