摘要：
In this work, a single band dielectric resonator antenna (DRA) operating in the 2.45 GHz Wi-Fi band has been proposed for radio frequency energy harvesting (RFEH) purposes. A cylindrical dielectric resonator made up of Rogers TMM10i (TM) material having a dielectric constant of 9.8 has been chosen for enhancing the antenna radiation. The radius and height of DR respectively are 10mm and 7mm The proposed DR is placed over a 1.6mm thick FR4 substrate with a dielectric constant of 4.4. The substrate dimension of 60mmx50mmx1.6mm is chosen for designing the antenna. Microstrip feeding is chosen for excitation purposes. A dumbbell-shaped slot is introduced into the ground plane helps in obtaining the desired resonance. The proposed antenna is compact that provides better impedance matching and impedance bandwidth performances. A special property such as the omnidirectional behavior of the proposed antenna helps in receiving ambient energy over all of its directions. Thus, it is suitable for RFEH purposes.
