A novel microstrip antenna for triple-band WLAN/WiMAX applications is presented. Based on a face-shaped slot, the antenna consists of a pair of symmetrical eye-like patches, a smilingmouth-shaped feeding line and a rectangular stub that looks like the fringe. The resonant mode at 3.5GHz is excited by the basic radiation patch with the face-shaped slot. By adding a rectangular fringe-shaped stub...

An important challenge in communication industry is to reduce the total size of devices. Similarly array size reduction has attracted increasing interest in recent years. Placing elements of an antenna array close to each other is certainly one way to reduce the total size of an array antenna. However, one of the factor called mutual coupling depends on inter element separation and relative ori...

A novel, compact, probe-fed microstrip patch antenna for operation in dual-polarization mode is proposed. The novel design is achieved by etching out a symmetric pattern of crossed slots from the surface of a square probe-fed patch. Reduction in patch size of up to 51% with respect to a traditional dual-polarized square patch operating at the same frequency is obtained. Results show linear pola...

This paper presents several microstrip patch antennas, for reception at X band. From passive and active single patches to active arrays, design, fabrication, integration and test are addressed.

This paper propose a new generation of antenna that applies Metamaterial properties at ground Plane. Paper also analyzed the performance of Microstrip Patch Antenna with and without using the Metamaterial structure. The works mainly include Metamaterial as Defected ground plane. All antenna parameters such as Return Loss, Gain, VSWR and Band width were measured. The main focus of this paper was...

This paper presents the design of a dual stacked microstrip antenna over the frequency range of 9.5–16 GHz. Investigations show that in the new structure the impedance bandwidth of the antenna is increased to 44% and the thickness of the antenna decreases to 0.14λ. Furthermore, the gain bandwidth of the antenna (above 8 dB) is increased to 5.1 GHz (40%).

In recent years, great interest was focused on microstrip antennas for their small and good performance. With the continuous growth of wireless communication communication equipment, there are higher and higher demands feed single layer compact rectangular microstrip antenna application is proposed in this paper. Two L slits are introduced at edge of the patch to reduce the resonant frequency. ...

The effects of a two-dimensional periodic dielectric substrate on the performance of a microstripfed wide slot antenna are investigated. The microstrip-feed and wide slot is placed on opposite sides of the periodic dielectric substrate. Method of Moment calculations using volume integral equations is employed to determine the effects of the substrate. It is proposed that by introducing a period...

In this paper we have analysed and designed a rectangular microstrip antenna. We analyzed micro strip antenna in IE3D by finite moment of method. In this paper we have compare and analyzed the micro strip antenna in infinite ground plane having dimension length, L = 700mil & width, W=800mil to the micro strip antenna in finite ground plane having dimension length, L = 1468mil & width, W=1568mil...

A Tri-Band I slotted rectangular patch microstrip antenna is presented in this paper .The antenna resonates at1.43 GHz, 5.16 GHz and 7.60 GHz frequencies. The antenna is fed with coaxial feed giving band widths of 10.52%, 7.20% & 30.83% for VSWR values less than 1.14.Theproposed antenna can be used for WLAN (Wireless Local Area Network) applications.
