The antenna is fabricated on a 30 × 30 mm substrate. The measured bandwidth and antenna gain are 7.5% and 4.2 dBi, respectively. Radiation patterns are almost omnidirectional in the H-plane. These properties and the compact and uniplanar structure make the antennas suitable for use as RFID tags.application/pdf983658 bytesapplication/pdfBandwidth; Directional patterns (antenna); Electric impedance; Radio; Robustness (control systems); Signal encoding; Substrates; Waveguides; Conformal structures; Frequency bands; Radio frequency identification systems; Supply chain management; AntennasBandwidth; Directional patterns (antenna); Electric impedance; Radio; Robustness (control systems); Signal encoding; Substrates; Waveguides; Conformal structures; Frequency bands; Radio frequency identification systems; Supply chain management; Antennasjournal article10.1049/el:200467802-s2.0-10944248823
