Abstr act:Presented a design method and debug technique of micro miniature loop antenna base on the RF chip of rfPIC12F675 produced by MICROCHIP Corp..Designing method,the way of getting the value of parameter,debugging technique of loop antenna on PCB and the notice when designing the PCB are expatiated by designing the PCB and schematic circuit diagram of loop antenna of rfPIC12F675. It is shown by test results that the loop antenna can eradiate effectively. And it is little- volume, low- cost and high- efficiency.
Key words:loop antenna,r fPIC,wir eless communication,RF
