This paper describes the performance analysis of different feeding technique for wireless microstrip patch antenna i.e for wi-max applications. In this paper four types of feeding techniques (Microstrip line feed, coaxial probe feed, proximity coupled feed and aperture coupled feed) are used. From the four feeding techniques, microstrip line and coaxial probe feeds are contacting scheme, in whi...

This paper presents a novel way for achieving endfire radiation pattern using microstrip patch antenna array. The extensively used microstrip patch antennas i.e. rectangular and circular microstrip patch antennas, either single patch or in an array configuration do not have an endfire radiation pattern. The antenna array presented in this paper is designed by changing the geometry of the antenn...

In this paper, compact notch loaded microstrip antenna is analyzed using Zeland IE3D simulator and circuit theory concept. Analysis on varying thickness, dielectric constant, length and width of the notch has been reported. The bandwidth obtained by the proposed antenna is about 41.8%. Key WordsWide band, Microstrip Patch Antenna, Return Loss, Dielectric Substrate.

A Microstrip Conformal Hexagonal Slot Patch Antenna fed by 50Ω microstrip line for various applications is presented in this paper. The strip loaded proposed antenna is fed through microstrip line to achieve proper impedance matching. Simulated results on High Frequency Structure Simulator software version 13 (HFSS 13) and CST10 are compared for FR4 – epoxiy substrate at different central angle...

Microstrip antennas are low in profile and light in weight and they are now developed for many applications. The main difficulty of the microstrip antenna is its narrow bandwidth. Several modern applications like satellite communications, remote sensing and multi-function radar systems will find it useful if there is a dual band antenna operating from a single aperture. Some applications requir...

This paper introduced a new low cost, compact and robust microstrip antenna based on metamaterial split ring resonator property to replace the existed antenna by small size and multiband Frequency antenna. The proposed antenna is designed with multi rectangular patches and simulated for different frequency. By using the metamaterial property, the bandwidth of the antenna has been improved. The ...

Analysis and design of the planar microstrip antenna have been discussed in the preceding chapters. Planar microstrip antenna by and large can be considered to have reached its maturity. Development of conformable antennas on non planar surfaces lags behind vis-à-vis planar microstrip antennas. Relatively non planar or microstrip antennas conformable to non planar surfaces are at present topic ...

A novel dual-band microstrip antenna for an internal notebook antenna for WLAN operation is presented. The antenna has a simple structure consisting of a spiral strip. The proposed antenna has a low profile and can easily be fed by using a 50 Ω microstrip line. It is believed that the size of the antenna is about the smallest among the existing internal laptop antennas for 2.4/5.8GHz WLAN opera...

Microstrip patch antenna becomes very popular day by day because of its ease of analysis and fabrication, low cost, light weight, easy to feed and their attractive radiation characteristics. Although patch antenna has numerous advantages, it has also some drawbacks such as restricted bandwidth, low gain and a potential decrease in radiation pattern. In recent years, attention to use Electromagn...

This paper proposed a microstrip antenna array with DGS (Defective Ground Structure). The structure in this work is 2*1 microstrip patch array antenna using substrate with h= 0.762 mm and εr = 3.2. Two triangular-shaped patches are located on opposite side of PCB and spaced 14mm apart by a small ground portion. The proposed DGS of I-shape is placed in the ground plane. It does provide a method ...
