Modified EH shaped microstrip antenna for wireless systems
2009 International Conference on Networking, Sensing and Control, 2009•ieeexplore.ieee.org
A wideband L-probe fed microstrip patch antenna with low cross-polarization is proposed
and designed. By employing L-shaped feed and modification of EH shaped patch, an
antenna with 27%(550 MHz) impedance bandwidth (VSWRles2) and 9.33 dBi gain with gain
variation of 1.21 dBi is designed. It is shown that the wide bandwidth is caused by a two-
frequency resonance. The far field radiation patterns of the antenna are similar to those of
conventional patch antenna and stable across the operating bandwidth.

A wideband L-probe fed microstrip patch antenna with low cross-polarization is proposed and designed. By employing L-shaped feed and modification of E-H shaped patch, an antenna with 27% (550 MHz) impedance bandwidth (VSWRles2) and 9.33 dBi gain with gain variation of 1.21 dBi is designed. It is shown that the wide bandwidth is caused by a two-frequency resonance. The far field radiation patterns of the antenna are similar to those of conventional patch antenna and stable across the operating bandwidth.
