چکیده
In this article, a new small size planar microstrip tree profile shaped Ultra-Wide Band (UWB) antenna with partial ground plane has been presented. The is designed for chipless RFID tags that are working in UWB region. operating frequency of the between 2.72 GHz to 11.1 which covers entire band. exhibits comparatively high realized gain 4.2 dBi respect its 27 × 40 mm2 and have aperture ratio 0.243 higher than other existing retransmission-based antennas. Another aspect total efficiency never goes below 80% throughout bandwidth whereby it reaches as 96% at 3.5GHz. This design will motivate designers produce cost effective tags.

Chipless Rfid Tags
a compact multi resonator circuit for Chipless rfid tag is presented in this paper. The basic resonator is a shorted λ/4 Stepped Impedance Resonator (SIR). The tag is designed and simulated using High Frequency Structure Simulator and a 6 bit prototype is fabricated on rtduroid(εr=2.2 and tanδ=.0008) Substrate in area of 4.5x2cm2. Data is coded as amplitude variations in the frequency domain. H...
متن کاملA Coplanar Waveguide Fed Hexagonal Shape Ultra Wide Band Antenna with WiMAX and WLAN Band Rejection
In this paper, a coplanar waveguide (CPW) fed hexagonal shape planar antenna has been considered for ultra-wide band (UWB). This antenna is then modified to obtain dual band rejection. The Wireless Local Area Network (WLAN) and Wireless Microwave Access (WiMAX) band rejections are realized by symmetrically incorporating a pair of L-shape slots within the ground plane as well as a couple of I-sh...
