A annular slot antenna with cross-shaped feedline has been investigated experimentally to obtain a large bandwidth enhancement. The voltage standing wave ratio (VSWR), radiation pattern, and antenna gain of this configuration are presented. Although the use of a high relative permittivity (ɛr=4.3) substrate usually restricts the operation bandwidth, the radiation resistance also was a low value. The measured bandwidth is ∼108.4% (2.0≥VSWR).
