Abstract
A novel design of a slot antenna has been proposed with meandered slots for Bluetooth application. The antenna is designed for higher frequencies in order to reduce its size and, by using meandered slots, frequency shifting is achieved. Using four meandered slots, the frequeney is reduced to the desired application range, that is, 2.4-2.48 GHz. It is experimentally verified that the size of the antenna is reduced by 31.5%. The 10-dB return-loss bandwidth is 100 MHz or 4.16% and the gain of the antenna is 4 dB. The 3-dB axial-ratio bandwidth is 3.2%. The antenna performance is further enhanced by introducing ail electromagnetic band gap (EBG) structure. Kaiser-distributed EBGs have a higher return loss as compared to uniformly distributed EBGs. The antenna is tested oil a Bluetooth transceiver and the range is increased to 22 in using the ROK1001008 Bluetooth module chip. (c) 2006 Wiley Periodicals, Inc.
