Abstract
This paper presents the design of a high gain cross DRA array antenna (AXDRA) with a novel feeding method based on microstrip transmission line for millimeter-wave operation. Simulation results shows that the AXDRA achieves an impedance bandwidth from 57.5 GHz to 63 GHz covering ISM band, and gives an appreciable gain of 15.5 dBi, found to be stable within the passband. The size of the whole antenna structure is about 25mm×25mm and is therefore small enough to be used in underground communications systems. The simulation process was done using Computer Simulation Technology (CST) Microwave Studio.
