Description

Antenna apparatus

The present invention relates to an antenna device.

Data traffic of mobile communication is rapidly increasing every year. Active technology development is in progress to support this breakthrough data in real time in the wireless network. For example, contentization of IoT (Internet of Thing)-based data, AR (Augmented Reality), VR (Virtual Reality), live VR/AR combined with SNS, autonomous driving, Sync View (User's point of view using a small camera) Applications such as real-time video transmission) require communication (eg, 5G communication, mmWave communication, etc.) that supports sending and receiving large amounts of data.

Therefore, recently, millimeter wave (mmWave) communication including fifth generation (5G) communication has been actively studied, and research for commercialization/standardization of an antenna device that smoothly implements the same is being actively conducted.

Since RF signals in high frequency bands (eg, 24 GHz, 28 GHz, 36 GHz, 39 GHz, 60 GHz, etc.) are easily absorbed and lost in the course of transmission, the quality of communication may drop sharply. Therefore, an antenna for communication in a high frequency band requires a technical approach different from that of the existing antenna technology, and a separate method for securing antenna gain, integrating antenna and RFIC, and securing EIRP (Effective Isotropic Radiated Power), etc. It may require the development of special technologies such as power amplifiers.

During remote transmission/reception of an RF signal, most of the surface current corresponding to the RF signal may flow through the upper and lower surfaces of the first patch antenna pattern 111a, and the surface current is generated by an electric field in the same first horizontal direction as the direction of the surface current. may be formed, and a magnetic field may be formed in a second horizontal direction perpendicular to the direction of the surface current, and most of the RF signal may be formed in a vertical direction (eg, z direction) perpendicular to the first and second horizontal directions. It can propagate through air or through dielectric layers.

Accordingly, the radiation pattern of the first patch antenna pattern 111a may be intensively formed in the normal direction (eg, z-direction) of the upper and lower surfaces of the first patch antenna pattern 111a, and The gain may be improved as the radiation pattern concentration of the first patch antenna pattern 111a increases.

Since the ground plane 201a can support the concentration of the radiation pattern of the first patch antenna pattern 111a by reflecting the RF signal, the gain of the first patch antenna pattern 111a can be further increased, and the first It is possible to support formation of an impedance corresponding to the first resonant frequency of the patch antenna pattern 111a.

The surface current flowing in the first patch antenna pattern 111a may be formed based on a feeding path provided to the first patch antenna pattern 111a.
