Narrowband antennas fail to radiate short pulses of nano-or picosecond length over the
broader band of frequencies. Therefore, Ultrawideband (UWB) technology has gained …

The growing demand for space-efficient antennas compatible with portable electronic
gadgets inspired the integration of recursively iterated fractal geometries (characterized by …

A compact triple band antenna with stacked T-shaped strips inside a rectangular ring
monopole has been proposed. This novel structure with a slot in the defected ground …

This paper presents a low-profile, isolation-enhanced, multiple-input multiple-output (MIMO)
antenna with a band-notch feature. The MIMO structure comprises two fractal-shaped slotted …
