We have a requirement for an antenna that would operate within a bandwidth of 865-867 MHz, to support our metering application. We are about to layout our board but antenna selection is something we would like to pay more attention to before we actually get started with the layout design.
The target dimension of our PCB is 50x30 mm that integrates to smart meter and serves as communication module to it. As you may have already figured that PCB is small form factor and hence antenna efficiency becomes more critical here. So, I kindly request you to help us with the range of antennas that are applicable to said bandwidth. We would like to share our design files with you too, so we can have a quick simulation run, to find out efficiency in ideal scenario.
