在本研究中，提出了单频和双频微带天线的高阶模式抑制技术。该技术在微带天线内集成了微带滤波器，从而无需单独的滤波器，从而简化了发射器/接收器链。该技术使用低通微带滤波器提供 8 dB 的高阶模式抑制，而不对天线的谐振频率和增益产生任何影响。利用该技术设计了S、X频段双频天线，在S频段获得了7%的测量带宽和8dBi的增益，在X频段获得了10.5%的测量带宽和11.5dBi的增益。该天线可用于卫星应用。
In this study, a higher-order mode suppression technique in single- and dual-frequency microstrip antennas is proposed. The technique integrates a microstrip filter within the microstrip antenna, thereby simplifying the transmitter/receiver chain by eliminating the need of a separate filter. This technique gives higher-order mode suppression of 8 dB using a low-pass microstrip filter without any effect on the resonance frequency and the gain of the antenna. A dual-frequency antenna for S and X bands is designed using this technique to obtain measured bandwidth of 7% and gain of 8 dBi at the S-band and measured bandwidth of 10.5% and gain of 11.5 dBi at the X-band. This antenna can be used for satellite applications.
