Abstract :
This paper presents two type of one layer wireless pad using microstrip structure. First, we discuss a wireless pad using a microstrip filter geometry. To decrease its polarization dependence loss, we change the geometry of filter arrangement and receiving antenna structure. Next, we examine circularly polarized feeding antennas for RFID antennas with a freedom of its orientation and polarization. We discuss these wireless pads to obtain uniform coupling level between the pad and RFID antenna in the followings.
