Abstract

An equivalent electrical lumped component modeling of E-shaped patch flat lens antenna unit cell was designed and analyzed in this paper. The proposed element model consists of two identical circuits connected by a coupling transformer. The lumped component parameters were determined analytically considering the physical structure of the unit cell at 4.2 GHz. The circuit was implemented and simulated using MULTISIMV10 software. The transmission loss and reflection loss performance of the unit cell can be controlled by adjusting the values of inductance (Lp) and capacitance (Cp) at the resonance frequency. A low transmission loss of 2.8 dB and a large phase shift range of 320º were achieved. The theoretical results were compared with the CST Microwave Studio simulations and a good agreement was obtained.
