A panel antenna is an antenna that uses a panel structure and has the following characteristics:
1. Ultra-thin design: The planar antenna uses one or several layers of ultra-thin dielectric substrates, whose size is usually much smaller than that of traditional antennas and its weight is also relatively light, making it suitable for use in environments with limited space or weight restrictions.
2. Wide band performance: The bandwidth range of the planar antenna is wide and can meet various application requirements. Additionally, its actual bandwidth can be adjusted by slight tuning of its geometric dimensions or structural parameters.
3. High efficiency: The radiation efficiency of the planar antenna is higher than that of traditional antennas and can be improved by optimizing its design to enhance transmission efficiency.
4. Multi-functionality: The planar antenna can be used in a variety of communication systems, including communication, radar, and satellite communication.
