\begin{abstract}
\selectlanguage{ngerman}\textbf{In this paper, two new compacts halved size single and UWB
antennas are proposed for WiFi and UWB applications. The single-band
compact halved size slot antenna is proposed for WiFi applications at
2.4 GHz. The resonant frequency of the conventional slot antenna can be
reduced by cutting the antenna into two halves and without using any
lumped elements inside the slot. Moreover, the impedance and radiation
characteristics of the proposed halved-size antenna are suitable for
WiFi applications at 2.4 GHz. The proposed WiFi antenna has a
miniaturized size of 25 × 16.5 × 0.813 mm\textsuperscript{3}. Then, an
octagonal blended-shape antenna (OBSA) for UWB applications is
proposed.} \textbf{By applying the same cutting concept, the halved size
OBSA covers the UWB band from 3.1 GHz to 10.6 GHz. Furthermore, a
grounded L-stub is added on the top side to improve the reflection
coefficient. The proposed OBSA has a compact size of 28 × 13 × 0.813
mm\textsuperscript{3} with stable omnidirectional radiation patterns.
Simulation and measured results are in good agreement.}%
