Abstract
An ultra-wideband slot antenna realised in low-temperature cofired ceramic (LTCC) technology is reported. The antenna is developed for a single-package solution of ultra-wideband radio. The radiating element of the antenna has a shape of ellipse 11 mm wide and 17 mm long. It shares the ground plane with other radio circuitry and is fed through a microstrip line 41 mm long and 3 mm wide. The experimental result shows that the prototype antenna achieved a bandwidth of 7.6 GHz (return loss S11≤−10 dB or VSWR 2:1 from 3 to 10.6 GHz). The antenna radiation patterns at 3.5, 6.85 and 10.1 GHz are also presented.
