Bandwidth enhancement of compact microstrip rectangular antennas for UWB applications

According to the FCC regulations, the effective isotropic radiated power (EIRP) less than -41.3 dBm/MHz, so the UWB signal has less power than the noise levels. [...]the DGS in the ground plane plays an important role in microwave circuits and devices to make the system compact, effective and high performance [17-19]. [...]to lead to practical designs of rectangular microstrip antennas, there's a design procedure. The measurement results show goodagreement with simulation in term of bandwidth. [...]these antennas are suitable candidates for UWB bands applicationsand can easily be integrated with RF/microwave circuits for compact design and fabricated at a very low manufacturing cost.
