摘要： A unified circuit without using a relay is proposed to resonate an antenna at more than two frequencies. The use of such analog IC switches are common place for transceiver applications in high RF frequencies (500 MHz and above). However, the use of selectively tuned antennas has for the most part been accomplished by the use of latching relays or fixed value components. The IC switch allows for not only the functionality of a single antenna to be either a transmitter and/or a receiver, but also allows, by adding additional switches to select any number of frequencies to resonate the antenna. This frequency resonation could be at fixed frequency points or sweep in either linear or logarithmic steps. The component selection of capacitors for either method would be controlled by a DSP or other microcontroller device. In one embodiment, an antenna for a downhole measurement tool is provided with a tuning circuit couple by a transformer to at least one antenna. The tuning circuit is disposed entirely within and protected by the hollow body of the tool and selectively tunes the antenna to at least three discrete frequencies. Advantageously, no structural modification is made on the outer surface of the tool to accommodate the tuning circuit. In one embodiment, a switching circuit enables a single antenna to function as both a transmitter and a receiver.
摘要翻译：提出一种不使用继电器的统一电路，以便在两个以上的频率下谐振天线。使用这种模拟IC开关是在高RF频率（500MHz及以上）中的收发器应用的常见之处。然而，使用选择性调谐天线大部分是通过使用闭锁继电器或固定值组件来实现的。 IC开关不仅可以将单个天线的功能作为发射机和/或接收机，而且还可以通过添加附加开关来选择任意数量的频率来谐振天线。该频率谐振可以在固定频率点或以线性或对数步长扫描。任何一种方法的电容器的组件选择将由DSP或其他微控制器设备控制。在一个实施例中，用于井下测量工具的天线设置有由变压器耦合到至少一个天线的调谐电路。调谐电路完全设置在工具的中空体内并由其保护，并且选择性地将天线调谐到至少三个离散频率。有利的是，在工具的外表面上不进行结构修改以容纳调谐电路。在一个实施例中，开关电路使得单个天线能够用作发射机和接收机两者。
