摘要
设计了一种用于2.4 GHz无线语音的IFA(Inverted-F Antenna)天线,该天线能够满足2.4 GHz频段无线语音传输对天线尺寸、价格和性能的要求。使用有限元法进行数值仿真和设计,该天线可达到较好的效果。该天线的仿真和实测结果表明,在2.46 GHz的中心工作频率下,回波损耗为19.9 dB,带宽约为500 MHz,满足了IEEE 802.15.4协议的要求。
An inverted F antenna is proposed for wireless audio applications. It satisfies the requirement of size, cost, and performance for wireless audio. The performance of the antenna can be exeellented by numerical simulating and designing using finite element method. The antenna operates at 2.46 GHz with a return loss of - 19.9 dB and a bandwidth of 500 MHz, which suits the requirements of the IEEE 802.15.4 protocol.
