Abstract

A compact ultra‐wideband (UWB) antenna with size of 17 × 10 × 1 mm^3^ in low‐temperature co‐fired ceramic (LTCC) technology is designed, fabricated, and tested. It achieves impedance bandwidth of 6.7 GHz from 3.5 to 10.2 GHz. The measured antenna radiation patterns at 6.85 GHz are also presented. The antenna is further studied for a single‐package solution of UWB radio transceivers. The integration is analyzed with an emphasis on the connection of the antenna to the transceiver die. The final integrated UWB antenna has size of 20 × 10 × 1.2 mm^3^ and achieves impedance bandwidth of 6.7 GHz from 5.05 to 11.75 GHz with available radiation patterns. It also achieves the radiation efficiency of >96% and the gain of 2.5 to 4.3 dBi over the simulated UWB frequency range. © 2008 Wiley Periodicals, Inc.
