Microstrip antennas and arrays have been widely used in military and commercial applications because of their ease of fabrication, low profile and low cost. In any microstrip array antenna, design of the feed network is always the most challenging task for which many different methods have been proposed. One method is to distribute the power to individual array elements by a coplanar microstrip...

This paper presents the design and results of a compact tapered U slot UWB printed monopole microstrip antenna. The planar, very small, thin UWB antenna fed by a single 50? microstrip line with truncated ground plane is excited by a coaxial SMA connector. The simulation was done using Ansoft High Frequency Structure Simulator (HFSS) software. Extensive investigations and parametric analysis is ...

In this paper, a microstrip patch mounted on high impedance substrate with hexaferrite cavity is proposed. The proposed antenna design is simulated on electromagnetic (EM) simulation software using FR-4 substrate with dielectric constant of 4.4 and thickness of 1.60mm. The proposed antenna has a compact structure with a total size of 50.8x50.8mm. A microstrip fed low profile broadband dielectri...

---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). ...

Microstrip patch antenna has attracted wide interest due to its important properties such as light weight ,low profile ,simple to fabricate and easy to integrate with RF devices. In this paper very small size triangular microstrip antenna is designed by using method of moments (MoM) based IE3D software for wireless communication. The proposed antenna is compact, small, simple to design and fabr...

In this paper, a new design of a frequency reconfigurable microstrip antenna by using microstrip line feeding for UWB applications is presented. The process of frequency band rejection is done through the slots on the radiation patch and ground plane of antenna. Also the antenna bandwidth has been improved by using partial Defected Ground Structure (DGS). Then by putting two switches on the gro...

A new type of a dual-frequency and dual-linear-polarization multilayer stacked microstrip antenna element is presented. The feeding mechanism of the element is aperture coupling for one polarization and direct feeding for the orthogonal polarization. The microstrip element exhibits a wide band of operation, high isolation between ports, and high radiation efficiency for both polarizations compa...

In this paper we propose an antenna geometry whose structure embodies dual stacked circular patches printed back to back on a single substrate in inverted microstrip configuration offering wideband performance suitable for mobile communication systems. The structure offers easy integration with active devices due to its inverted configuration as well as wide bandwidth without any enhancement in...

A planar magnetoinductive (MI) waveguide loaded rectangular microstrip patch antenna is presented and discussed. The MI waveguide consists of two planar metamaterial split squared ring resonators (SSRRs) placed in between two microstrip lines. The backward wave propagation takes place through this structure. The rectangular microstrip patch antenna is magnetically coupled to the MI waveguide. T...
