Abstract EN
The RF front-end performances in the far-field condition of reconfigurable antennas employing two commonly used RF switching devices (PIN diodes and RF-MEMS switches) were compared.
Two types of antennas (monopole and slot) representing general direct/coupled feed types were used for the reconfigurable antennas to compare the excited RF power to the RF switches by the reconfigurable antenna types.
For the switching operation of the antennas, a biasing circuit was designed and embedded in the same antenna board, which included a battery to emphasize the antenna’s adaptability to mobile devices.
The measurement results of each reconfigurable antenna (radiation patterns and return losses) are presented in this study.
The receiving power of the reference antenna was measured by varying the transmitting power of the reconfigurable antennas in the far-field condition.
The receiving power was analyzed using the “Friis transmission equation” and compared for two switching elements.
Based on the results of these measurements and comparisons, we discuss what constitutes an appropriate switch device and antenna type for reconfigurable antennas of mobile devices in the far-field condition.
