A Deeper Study on Antenna Radiation Frequency

Studying foundational knowledge is essential, as it can help us create new things or find more effective problem-solving methods. This work further displays and validates some characteristics of antenna radiation frequency by software and published experimental data from other literature. Firstly, the radiation frequency of antennas is continuous. Secondly, the bandwidth and gain of antennas have a mutual constraint. Then, antennas with complex structures exhibit wider operating frequency bands. Finally, antennas display a broader bandwidth with a shorter periodic time of excitation signals. This work is meaningful, it can help people better design and use antennas in practice.
