Abstract
A MIMO antenna system that consists of four-element Vivaldi antenna for V2V communication is presented. The proposed design is realized on a substrate material of “Rogers 5880” with , , and a substrate thickness equals . The antenna is designed to operate at a center frequency of . The designed antenna achieves a wide bandwidth of around the center frequency. The radiation pattern of the proposed structure covers all the directions (a full coverage area) with high gain. An overall realized gain of is achieved at the intended center frequency. The proposed antenna is designed and simulated using the Computer Simulation Technology MicroWave Studio software (CSTMWS). It is also fabricated using photolithography techniques and measured using an R&S vector network analyzer. Good agreement is obtained between both the CSTMWS and the measured results.
