Printed dipole antenna for use in wireless networks: techniques for the design improvement

In this paper, new methods are proposed to reduce the size of a popularly used printed microstrip dipole antenna by 60%. Most antenna parameters such as efficiency, gain, and radiation pattern are unaffected by the size reduction. The key undesired consequence of the miniaturization process is the decrease in bandwidth. This paper demonstrates that the lost bandwidth can be recovered by some simple design techniques. To test the functionality of the miniaturized dipole antenna, it is integrated with a Zigbee wireless transceiver on the same PCB.
