Microstrip antennas have been widely used for aerospace applications and in small portable wireless communication equipments because of their compactness, light-weight, low-profile, and relative ease of fabrication. The small size is an important requirement for portable applications. There are various types of microstrip patch configurations. In general, the size of a microstrip patch is about...

Methods for reducing Radar Cross Section (RCS) of objects have been investigated by many researchers both experimentally and theoretically for the last so many years. This chapter presents a chronological review of important research in the fields of RCS studies, RCS reduction techniques and fractal based scattering and radiating structures. This chapter is divided into two sections. The first ...

In this paper, we have designed rectangular ring Microstrip antenna for UWB wireless applications. The beauty of this antenna is the use of single patch which make it easy to fabricate consequently cost of antenna becomes cheaper. It has no misalignment problem, Bandwidth enhancement is achieved due to employment of matching rectangular strips. Return loss at centre frequency is less than -15dB...

Here we made an attempt to maximize the gain of microstrip patch antenna. To achieve this we used microstrip circular patch antenna at 5.8 GHz frequency ISM Band Application. Single FSS (frequency selective surface) substrate is used to increase efficiency. Parameters are set accordingly and results of microstrip patch antenna with FSS layer and microstrip patch antenna without substrate later ...

A topology optimization method is proposed in this study to miniaturize a Rectangular Microstrip Patch Antenna (RMPA) operates at a frequency of 2.4 GHz using Metamaterials (MTMs) composed of complementary resonator. The metamaterial is placed in an intermediate layer between the patch and the ground, binary pixelation approach is used to build the structure of the complementary resonator and i...

An effective approach to reduce the patch size in rectangular patch microstrip antennas is presented. The proposed approach is based on inductively loading the patch using a cuboid ridge. A theoretical background of the approach using the transmission line model has been provided. A prototype of the proposed antenna is fabricated and measured. The results, advantages and limitations of the prop...

In this paper, a probe-fed rectangular microstrip patch antenna with partially reflective superstrate at terahertz frequency (600GHz) has been analyzed and simulated. The analysis of the partially reflective surface shows the highly reflective property of the surface over the wideband of the frequencies. The analysis of a specific configuration (rectangular patch) of partially reflective surfac...

A simple electromagnetically coupled broadband printed microstrip antenna suitable for multifunctional wireless communication bands is presented. V-slots and corner notches are employed in a rectangular patch to achieve broadband operation. The proposed antenna has a 2 : 1 VSWR bandwidth of 51% from 3.75 GHz to 6.33GHz. The simulated and measured reflection characteristics of the antenna along ...

This paper focuses on the development of a novel single layer dual band proximity fed gap coupled microstrip array antenna. A basic 2x1 microstrip patch array consisting of a pair of rectangular patches which are coupled with a centrally placed microstrip line in the same plane and an arrow headed dumbbell shaped slot in the ground plane is investigated. By using two additional parasitic patche...

This paper presents new form of artificial neural network description (ANN) for the estimation of bandwidth of a coaxial feed rectangular microstrip patch antenna. The results obtained using ANNs are compared with the IE3Dsimulation and found quite satisfactory. The designed antenna operates in the frequency range of 1.90 to 2.27 GHz and 3.052 to 3.570 GHz. The antenna is designed using air as ...
