This paper presents the design of an optimal microstrip patch antenna array for use with handheld units. The Array consists of two elements. Design structure, size and performance parameters of the antenna elements/array are optimized. This antenna array can provide good properties required for personal handy phones. It has wide bandwidth with steerable radiation pattern and can adjust its patt...

Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...

a new multiple c- slotted microstrip patch antenna is proposed.  a patch antenna is a wide-beam narrowband antenna. microstrip patch antenna consist of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. the patch can be designed in any possible shape and normally made by conducting material copper or gold. this paper presents design of a c- slotted ...

This paper presents microstrip array antenna integrated with novel shapes of 2D-electromagnetic band-gap structure (2DEBG). Three different shapes of 2D-EBG are used for harmonic suppression, optimizing the current distribution on the patches and decreasing the mutual coupling between array elements. As a result, the performance of the antenna array is improved. The three novel shapes of 2D-EBG...

A low cost 4  4 butler matrix fed antenna array has been proposed for Ku band applications. At high frequencies, the ohmic and dielectric losses are high and also the undesired feed radiation is more in the case of microstrip line feed, therefore substrate integrated waveguide (SIW) has been used to feed the antenna elements. The implementation of SIW technology improved the radiation performa...

A complete multiple-input multiple-output (MIMO) communication system with orthogonal frequency-division multiplexing (OFDM) based on multiple excitation modes for a single circular microstrip antenna is introduced. Traditional diversity techniques such as spatial diversity by means of a linear antenna array or polarization diversity by means of a crosspolarized antenna array may prove to be un...

---This paper proposes a technique which improves Directivity and control of Beam-Steering by including metamaterial surfaces onto microstrip patch antenna superstrate used for wireless communication applications. Metamaterials are designed with Artificial Magnetic Conductor (AMC), inductive and capacitive planar structures. These structures allow obtaining Partially Reflective Surfaces (PRS). ...

This paper describes the design of a compact, M-code capable, four element GPS adaptive antenna arrays made from stacked patch microstrip antenna elements. Possible applications for these antenna arrays are in military airborne platforms where the space available for installing antennas is very limited. To meet future GPS M code requirements, the antenna elements were designed for a bandwidth o...
