Description

Antenna element, communication device and method of manufacturing antenna element Technical Field The present disclosure relates to the field of antennas, and more particularly, to antenna elements, communication devices including antenna elements, and methods of manufacturing antenna elements. Background An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. In a radio device, an antenna is used to transmit or receive electromagnetic waves. Antennas are mainly classified into two major categories, namely omni-directional antennas and directional antennas, according to the concentration degree of the patterns of the antennas. The omnidirectional antenna is uniformly non-directional in radiation intensity in a specific plane (e.g., horizontal plane). The directional antenna radiates energy concentrated in one or more specific directions to form a sharp "beam". Common omni-directional antennas include dipoles, monopoles, and the like. Common directional antennas include microstrip antennas and the like. Communication devices such as routers typically use dipole antennas or microstrip antennas to transmit or receive electromagnetic waves. Disclosure of Invention Based on the above, the present disclosure provides an antenna element, a communication device including the antenna element, and a method of manufacturing the antenna element. In one aspect, the present disclosure provides an antenna element including a substrate and a conductive layer on the substrate, the conductive layer including a first radiating element and a second radiating element forming a feed gap therebetween, the feed gap having an open end and a closed end, a third radiating element and a fourth radiating element connected to both sides of a closed end periphery of the feed gap, respectively, and the third radiating element and the fourth radiating element being inclined with respect to the feed gap. In one aspect, the present disclosure provides a communication device including an antenna element according to an embodiment of the present disclosure. In one aspect, the present disclosure provides a method of manufacturing an antenna element, including providing a substrate, providing a conductive layer on the substrate, and etching the conductive layer to form a first radiating element and a second radiating element, the first radiating element and the second radiating element forming a feed gap therebetween, the feed gap having an open end and a closed end, a third radiating element and a fourth radiating element, the third radiating element and the fourth radiating element being respectively connected to both sides of a periphery of the closed end of the feed gap, and the third radiating element and the fourth radiating element being inclined with respect to the feed gap.
