This paper covers two aspects of microstrip antenna design. The first is the analysis of trapezoidal patch microstrip antenna with V-shaped slot which operate at the centre frequency of 5.5 GHz. The second aspects are the analysis and design of inverted V-shaped slot cut trapezoidal microstrip antenna operates at centre frequency of 4.1 GHz. The simulation has been done through IE3D simulator. ...

In this paper, the bandwidth of rectangular Microstrip antenna is enhanced by ‘I’ slotted rectangular microstrip patch antenna. In some applications which the increased bandwidth is needed, proposed antenna is one of the alternative solutions. The proposed antenna has been designed at the 2 GHz frequency. The frequency band of proposed antenna is in between (1.64-3.26 GHz) the fractional bandwi...

Computation of the broadband matching potential of a microstrip antenna requires the wideband lumped equivalent circuit of the antenna. The general topology of the equivalent circuit of rectangular microstrip patch antennas has been used to model the feedpoint impedance of microstrip antennas over a wide frequency band and equivalent circuit parameters are determined using optimization techniqu...

A 2.45-GHz microstrip patch antenna was designed for small-satellite communications. Optimization was achieved by trimming the copper patch to minimize the input return loss over the desired 2:1 VSWR bandwidth. Final testing of the antenna included a successful long-range data transmission over which pictures taken by the satellite were sent to the ground station. In addition to the microstrip ...

The paper summarize that moisture sensor based on microstrip patch antenna. Microstrip patch sensors have become useful and widely used in every fields such as agricultures, industrials, food products, medicals communication etc. It have been more useful for detecting i.e., broken rice detection, Impurities detection in water, Soil moisture measurement, Rice Grain moisture, Rice quality detecti...

In this paper, we present a comparison between a double Lslot rectangular and circular microstrip patch antenna for worldwide interoperability for microwave access(WiMAX) 2.5/3.5/5.5 GHz and wireless local area network(WLAN) 2.4/5.2/5.8 GHz applications. The coplanar waveguide (CPW) fed microstrip patch antenna considered in our work. This design results in a reduction in size and weight and al...

The paper presents the performances of microstrip patch antennas excited by the aperture-coupling feed that is composed of a T-shaped microstrip feed line and an annular-ring slot. Because the annular-ring slot is designed at a full-wavelength resonant mode, a broad impedance bandwidth can be obtained by combing the resonant modes of the coupling slot and radiating patch; moreover, a low cross ...

Microstrip antennas are widely used in many applications due to their low profile, low cost and ease of fabrication. In some applications it is desired to have a dual band or multiband characteristics. These characteristics can be obtained by coupling multiple radiating elements or by using tuning devices such as varactor diodes [1, 2]. However, these methods make antenna more complicated. A si...

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...
