According to a study from the United States, "Metamaterial-inspired electrically small Z, stub and canopy antennas are reported. They are near-field, resonant parasitic designs."
"Different Z and stub antenna configurations and the effect on their Q values are studied. Their behavior led to the canopy antenna design. At the size of k alpha similar to 0.046, the canopy antenna is an electric-based antenna with high overall efficiency (over 90%) and low Q-ratio value and whose input resistance is almost completely matched to a 50 Omega source. The resonant frequency similar to 300 MHz, in the UHF band is selected for the designs. The canopy antenna is studied ...
