Abstract
A thin (only 5% of the operating wavelength, Ξ») wideband microstrip patch antenna with two closely spaced slots is introduced. When connected to each other, the two slots translate into two distinct resonant frequencies, resulting in wide impedance bandwidth (about 20% within 2:1 VSWR). Detailed design data, including resonance frequency, impedance, and bandwidth, are presented as function of the antenna and slot parameters. It is also demonstrated that such antennas can be designed at different frequency bands by appropriately adjusting the antenna and slot parameters. Β© 2004 Wiley Periodicals, Inc.

## Abstract A novel ultraβwide band printed slot antenna is presented. By using the novel feeding structure of a circular patch with a tapered microstrip line, the bandwidth of the elliptical slot antenna is greatly enhanced. The impedance bandwidth (VSWR < 2) reaches 174%, covering 1.90β27.7 GHz w
