本文提出一於FR4基板實現低損耗、面積小之2.4 GHz帶通濾波器,利用LC諧振方式設計帶通濾波器,實際量測的插入損耗在帶通頻段2.4 GHz為0.9 dB,帶通內漣波不超過1 dB,-3 dB頻寬為1.8 GHz(從900 MHz到2.7 GHz),截止頻帶從3.6 GHz到10 GHz可衰減至-20dB以上,其中5 GHz到7.4 GHz可達-30dB,電路面積為19.6mm*10.0mm,不需使用破壞地結構(defected ground structure),具低成本、面積小、特性好,可直接整合於2.4GHz頻帶之通訊系統。
This study proposed a low insersion loss and small area bandpass filter realized on Forgotten Realms 4 (FR4) substrate for 2.4 GHz applicaitons. For shrinking circuit area, the filter is designed with LC resonator structure, but without the defected ground structure (DGS) which is the most popular method to reduce area. Thus, the filter is shrunk without destory the ground. The measured insertion loss of the filter is 0.9 dB at 2.4 GHz, and the passband ripple is below 1 dB. The -3 dB bandwidth is as wide as 1.8 GHz (from 0.9 to 2.7 GHz). The filter in stop band attenuates larger than 20 dB. The attenuation from 5.4 GHz to 7 GHz is up to 30 dB. The chip area is 19.6 mm × 10 mm. The filter is low cost, small area, and good performance. The filter could be used directly in 2.4 GHz communication system.
