A microstrip patch antenna is designed that have metallic ring coplanar to radiation patch and defected ground structure to enhance the gain is proposed. The design forces conversion of the surface wave energy into the space wave energy by the scattering of surface waves from metallic ring. The metallic ring is placed around the metal patch at a distance of d1 from the edges of the metal patch ...

Abstract—The patch shape influence on the radar cross section (RCS) of a cylindrical microstrip antenna (CMA) is discussed. The RCS of the CMA is evaluated from a plane wave scattering problem solution to a cylindrical microstrip antenna. The method of moments is employed in the spectral domain using sub-domain basis functions. It is shown that the patch shape has a pronounced effect such that ...

Microstrip antennas are also known as printed antennas and they have a variety of applications in radar systems, microwave communication links, satellite communication systems, wireless and mobile communication systems, medical equipment, etc. In this paper, a model of inverted T-shaped slot rectangular patch antenna is designed and simulated to evaluate the performance. The proposed antenna is...

This work focuses on design and analysis of microstrip patch antenna as well as effect of slots made on patch antenna to improve the bandwidth. A microstrip line fed, dual slot, triple band, rectangular microstrip patch antenna is designed. The designed antenna is most suited for C band, X band and KU band applications. The return loss is below −10 dB in triple band with 1GHz bandwidth in the r...

A Comparative study of rectangular and circular shape microstrip fed patch antennas for bluetooth application is presented in this paper. The resonance frequency is chosen at 2.45 GHz which is suitable for industrial scientific and medical (ISM) band applications. Computer Simulation Technology (CST) microwave studio is used as the software environment to design and compare the performance of t...

A simple, compact, slot loaded stacked wideband microstrip patch antenna is presented in this communication. The radiating element consists of a rectangular patch with a Tshaped slot and is fed by a 50 Ω microstrip line. The proposed antenna is simulated using IE3D software, 12.32 version of Zeland. The simulated results show that the antenna can exhibit wideband characteristics. The impedance ...

In this paper a novel structure of metamaterial is proposed in order to miniaturize a rectangular microstrip patch antenna. The metamaterial is composed of two nested split octagons which are located on a 10 mmx10 mm Rogers RT/duroid 5880 with 0.7874 mm thickness and dielectric constant of 2.2. A 3X5 array of such metamaterials is placed on the patch antenna substrate. By using this metamateria...

The bandwidth in half wave or quarter wave length microstrip antennas is increased by using suspended configuration in which the radiating patch is suspended above the ground plane of finite air gap. While using thicker substrate, a closed form expressions for calculating edge extension length due to the fringing fields in shorted patch, is not available. In this paper, an artificial neural net...

Two compact and low loss dual-mode filters are proposed by using degenerate modes of slotted triangular microstrip patch resonators. The geometrical size and radiation loss of the triangular patch are reduced simultaneously by loading both horizontal and vertical slots. The resonant frequencies of two degenerate modes can be easily controlled by varying the dimensions and positions of the slots...
