Design of High-Isolation Polarization-Diversity Microstrip Antenna for 900MHz RFID
Main Article Content
Abstract
This paper presents an isolation improvement of a dual probe-fed microstrip antenna for polarization-diversity in RFID system in Thailand (920 - 925MHz). We use a microstrip antenna with an air gap. A polarization diversity microstrip antenna with 30 dB isolation using two orthogonal rectangular slots inserted into a square patch near a feed point. The measured results found to be the same as simulation results.
