Abstract:A cross-shaped microstripline-fed slot antenna of large bandwidth is described. The experimental bandwidth of the antenna is from 1.765 to 4.921 GHz, which is 98.59% for S/sub 11//spl les/-10 dB. The measured radiation pattern of the antenna is also presented. A microstrip-fed cavity-backed slot (CBS) antenna is a slot radiator backed by a rectangular cavity and excited by a microstrip feed line. CBS antennas 12,8,24, 23 are promising candidates used.

A NOVEL COMPACT ULTRA-WIDEBAND (UWB) WIDE SLOT ANTENNA WITH VIA HOLES

By D. Chen and C.-H. ChengFull Article PDF (473 KB)
Abstract:
A novel compact ultra-wideband (UWB) wide slot antenna with via holes is presented for UWB applications. The antenna is composed of a trapezoidal slot on the ground plane, a rectangular patch in the center of the slot and three via holes connecting the rectangular patch and the microstrip feed-line. The antenna is successfully designed, implemented, and measured. The measured results show that the proposed antenna with compact size of 27.0 mm×29.0 mm×1.0 mm achieves good performance, such as an impedance matching bandwidth of 111.7% ( S₁₁ ≤-10 dB), constant gain and stable radiation patterns over its whole frequency range.
