摘要： An encoded information reading (EIR) terminal can comprise a microprocessor electrically coupled to a system/data bus, a memory communicatively coupled to the microprocessor, an EIR device, a multi-band antenna, and a wireless communication interface. The EIR device can be provided by a bar code reading device, an RFID reading device, or a card reading device. The EIR device can be configured to output raw message data containing an encoded message and/or output decoded message data corresponding to an encoded message. The wireless communication interface can comprise a radio frequency (RF) front end electrically coupled to the multi-band antenna. The RF front end can comprise a micro-electromechanical (MEMS) filter array including one or more band-pass filter. Each band-pass filter of the MEMS filter array can be electrically coupled to a bias voltage source or an oscillating signal source. The RF front end can be electrically coupled to an analog-to-digital (A/D) converter and/or to a digital-to-analog (D/A) converter. The wireless communication interface can be configured to transmit radio signals in two or more frequency regulatory domains and/or receive radio signals in two or more frequency regulatory domains. The multi-band antenna can in one embodiment be provided by a meta-material antenna.
摘要翻译：编码信息读取（EIR）终端可以包括电耦合到系统/数据总线的微处理器，通信地耦合到微处理器的存储器，EIR设备，多频带天线和无线通信接口。 EIR设备可以由条形码读取装置，RFID读取装置或读卡装置提供。 EIR设备可以被配置为输出包含编码消息的原始消息数据和/或输出与编码消息对应的解码消息数据。无线通信接口可以包括电耦合到多频带天线的射频（RF）前端。 RF前端可以包括包括一个或多个带通滤波器的微机电（MEMS）滤波器阵列。 MEMS滤波器阵列的每个带通滤波器可以电耦合到偏置电压源或振荡信号源。 RF前端可以电耦合到模数（A / D）转换器和/或数字到模拟（D / A）转换器。无线通信接口可以被配置为在两个或更多个频率调节域中发射无线电信号和/或在两个或更多个频率调节域中接收无线电信号。在一个实施例中，多频带天线可由超材料天线提供。
