We propose a dual-band antenna using a crooked U-slot with radial stub feeding. This
antenna has a simpler topology than other antennas designed for realizing dual-band …

In this paper, a dual-band circularly polarized rectangular loop slot antenna with notched
hexagonal aperture fed by a microstrip line has been optimized for the UHF and microwave …

In this work, a quad-band antenna radio frequency identification (RFID) and worldwide
interoperability for microwave access (WiMAX) is introduced. It is designed by embedding …

A novel compact CPW-fed slotted patch antenna for quad-band operation is proposed. The
antenna is printed on a 25× 20 mm FR4 substrate with thickness of 1.6 mm and relative …

A compact quad-band circular slot antenna with two T-patch is present. The prototype of the
proposed antenna is designed to satisfy specific bandwidth specifications of current …

A slot antenna for dual-band and dual polarization with good port-to-port isolation is
presented. By means of tuning the size of I-shaped mental in the aperture, the proposed …

A dumbbell U-slot antenna using radial stub feeding is designed for millimeter-wave
applications. This antenna takes simpler topology than other antennas designed for …
