in this article, the linear array (with 20 elements in the horizontal orientation) of microstrip antenna is examined with horizontal polarization. the set includes three microstrip substrates. there is a power network in two lower substrates and microstrip patches in the upper substrate. excitation of patches has been done as coupled through the power network in two lower substrates. using the ...

In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...

This paper present a circular patch microstrip array antenna operate in KU-band (10.9GHz – 17.25GHz). The proposed circular patch array antenna will be in light weight, flexible, slim and compact unit compare with current antenna used in KU-band. The paper also presents the detail steps of designing the circular patch microstrip array antenna. An Advance Design System (ADS) software is used to ...

A method for increasing the bandwidth of microstrip array antenna by adding additional resonator, which is directly – coupled to the non – radiating edges of a radiating element is narrated. The experimental result of four elements non-radiating edge directly – coupled rectangular microstrip array antenna (FNCRMAA) shows wide band with bandwidth of 15.63 %. Further extending the elements of arr...

This article describes the design of single microstrip rectangular patch antenna and 1x1 microstrip rectangular patch antenna arrays operating at 2.4 GHz. Simulation result shows that 5.199 dB and 7.84 dB gain can achieved at frequency 2.4 GHz. Also simulation result show that the return loss is 18.809 at 2.360 GHz in 1x1 microstrip antenna array and current distribution and 3D radiation patter...

In this paper, the design of 4x4 smart antenna array antenna along with the butler matrix network which can be used for beamforming (pointing an antenna array). Unlike the conventional schemes where an array of microstrip patch antennas are used, the radiation becomes omnidirectional and therefore the power losses are more. In the proposed design, the designed antenna is operating at the freque...

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...
