Robot-Type Miniaturized Planar Ultra-Wideband Triple-Notch Antenna

In the article, the introduction of the robot-type three-notch antenna will be discussed. The antenna is printed on a dielectric substrate made of FR-4. The electromagnetic simulation software HFSS is used for modeling and analysis. and other methods to expand the bandwidth, the use of slotting and the introduction of branches. The bandwidth of the antenna is 3.5GHz-21GHz, and the maximum gain of the antenna is 5.78dB. The three notches are 5GHz-WLAN, 7/8GHz X-band uplink and downlink, and 12-14GHz of satellite communication Ku-band. The antenna has achieved the trend of miniaturization in the current era, and the size of the antenna is only $24.4\ast23.38\ast1.6mm^{3}$.
