Abstract
The revolutionary microstrip technology for wireless communication suffers from relatively large size and low radiation efficiency when modeled for the current challenging hardware. An efficient solution to this subject is the quasi-lumped element (LE) approach. Therefore, this manuscript is a tutorial on the progress in quasi-LE resonator antennas, and it has been transcribed as an introduction or assessment for the readers. The paper traces the LEs’ history and fundamental principles. The modeling procedures of the quasi-LE resonator and its essential outline are summarized. A review of the quasi-LE resonator antennas for 5.8 GHz applications has been presented. Measurement reports of a unique quasi-LE antenna are also illustrated. Finally, the intended methods are compared with other configurations while considering the several important performance parameters of antennas.
