Dual-Band Compact Array of Printed Dipole Antennas
Keywords:
Compact array, printed dipole antennaAbstract
Compact array of printed dipole antennas loaded with reactive elements is proposed. A novel and practical applications of the metamaterial (MTM) inclusion in dipole antenna designs is presented. The simulation results show a reasonable reduction in mutual coupling between antenna elements and provide a possible way to reduce the element separation. A prototype of the proposed array antenna is fabricated and tested. Measurement shows that the isolation with interantenna spacing of less than 0.075? (at f=0.9 GHz) through the first frequency band (811 MHz–955 MHz) is above 12.5 dB, while the proposed design provides more than 15 dB isolation with interantenna spacing of less than 0.133? at f=1.6 GHz (1325 MHz–1880 MHz).
