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 MULTISIM^V10 software. The transmission loss and reflection loss performance of the unit cell can be controlled by adjusting the values of inductance (L_p) and capacitance (C_p) at the resonance frequency. A low transmission loss of 2.8 dB and a large phase shift range of 320° were achieved. The theoretical results were compared with the CST Microwave Studio simulations and a good agreement was obtained.
