Microstrip antennas are low in profile and light in weight and they are now developed for many applications. The main difficulty of the microstrip antenna is its narrow bandwidth. Several modern applications like satellite communications, remote sensing and multi-function radar systems will find it useful if there is a dual band antenna operating from a single aperture. Some applications requir...

A new broadband multiple-input multiple-output (MIMO) antenna with good isolation and compact size is proposed. The proposed antenna consists of two G-shaped elements in the upper layer and two inverted L protrude branches and a T slot etched in ground which is used to reduce the mutual coupling. This planar antenna has a bandwidth of 100% with |S11| ≤ -10 dB from 2.26GHz to 6.78 GHz. The value...

A small wideband microstrip patch antenna is introduced. The antenna is designed to function in the 5-6 GHz wireless LAN bands. It achieves multi-band functionality through the addition of a slot to a square patch (21 mm by 21 mm by 2.6 mm). The proposed antenna also generates circular polarization and has a 3 dB axial ratio bandwidth of 2.8%. The impedance bandwidth of the antenna is more than...

Study of a novel design of dual-band folded antenna with an L-shaped slot on the ground plane has been proposed for wireless local area network (WLAN) applications. The proposed antenna occupies a low profile above the ground plane. This characteristic makes it suitable for laptop PC applications. The proposed antenna can provide two impedance bands at 2.4 and 5.2/5.8 GHz, which satisfies WLAN ...

Abstract—In this paper, new multiband fractal-like antennas are proposed. The proposed multiband antenna design is based on a methodology that utilizes the self transformation principle of fractallike rectangular profiles to generate multiband operation. The proposed monopole-type antennas are built on a partial ground plane and fed through a microstrip feed line. The analytical design procedur...

A compact microstrip-fed ultra-wideband (UWB) planar monopole antenna with dual band rejected characteristic is presented in this paper. By etching two identical complementary square split ring resonators (CSRRs) in the radiation patch, dual band rejections in the WiMAX and WLAN bands are achieved. The proposed antenna, with the size of 30×34mm2, has been design. And the simulated results show ...
