Abstract—This correspondence presents a planar antenna in low-temperature Z58X5"  
cofired ceramic technology for a single-package solution of -[4T  
ultrawide-band (UWB) radio. The antenna has an elliptical radiator fed G6q }o)[m)  
through a microstrip line. The radiator and the microstrip line share 1b`1{%  
the same ground plane with the other UWB radio circuitry. The experiments o]J{{M'E  
have been conducted. Results show that the prototype antenna IXMop7~  
has achieved bandwidth of 110.9%, gain from 1 34 to 5.43 dBi, broad n71r_S*  
patterns, and relatively constant group delay at frequencies from 3 to 10.6 VuhGx:Xl  
GHz. Furthermore, it is also found that the normalized antenna radiated }l(&}#dY  
power spectrum density basically conforms to the FCCs regulation on the =\&;Fi]  
emission limit of indoor UWB sy .. ?yrX)3hyH
