Enhancing the Microstrip Antenna Gain Using a Novel EBG Lens Based on a Single Layer

In this paper, an Electromagnetic Band Gap (EBG) lens of a single layer is invented to improve the gain of a circular truncated slotted square patch antenna. The proposed EBG lens is constructed from concave conductive patches. The EBG antenna performance in terms of S11, the boresight gain, and radiation patterns are reported and compared to the performance before introducing the EBG lens to identify the significant enhancements. The proposed EBG antenna is simulated numerically inside Finite Integration Technique (FIT) formulations of CSTMWS time domain (TD) solver. A significant gain enhancement of 11 dBi at 2.45 GHz and a front to back ratio (F/B) about 28 dBi are achieved after introducing the EBG lens. The antenna performance is validated using a frequency domain (FD) solver based CSTMWS formulations to obtain excellent agreements between the two invoked methods.
