Design and Performance Analysis of Microstrip Patch Array Antennas with different configurations

This abstract demonstrates simple, low cost and high gain microstrip array antennas with suitable feeding technique and suitable dielectric substrate for applications in the GHz frequency range. The objective of this paper is to design, and fabricate a 16 element rectangular microstrip patch array antenna. Therefore, a novel particle swarm optimization method based on IE3D was used to design an inset feed linearly polarized rectangular microstrip patch antenna array with sixteen elements. .Initially we set our antenna as a single patch and after evaluating the outcomes of antenna features; operation frequency, radiation patterns, reflected loss, efficiency and antenna gain, we transformed it to a 2x1 array. Finally, we analyzed the 2×2 array, then 4×2 array and finally 4 × 4 array to increase directivity, gain, efficiency and have better radiation patterns. The simulation has been performed by Zeland software version 14.0 and the desired antenna provides a return loss of -42.154dB at 2.45 GHz by using RT Duroid dielectric substrate with Є r = 2.45 and height , h= 1.58mm. The gain of the antenna is found to be 19.455 dBi and the side lobe is maintained lower than the main lobe. Since the resonant frequency of these antenna is around 2-4 GHz, so these are suitable for Sband applications and can be used in WLAN communication systems. .

Study of Impedance-matching and Other Characteristics of Microstrip Antennas

Journal of Computer Science and Information Technology, 2015

In this paper I present the study and techniques used to find the modes of a microstrip patch antenna, match the antenna to the feed line and to measure the most important characteristics of the antenna (input response, far-field radiation patterns and polarization). The operating frequency of the antenna was found to be 1765MHz and a reflection coefficient of-65.46dB at 6.79mm from the edge of the rectangular antenna. The-10dB bandwidth of the antenna was found to be 83MHz and the wideband frequency response also shows various modes (1770MHz,-40.56dB; 2260MHz,-15.46dB; 2960MHz,-12.79dB; 4450MHz,-15.29dB). For the far-field radiation pattern, the half-power beamwidth for the E-plane and H-plane were found to b e 99 0 and 63 0 respectively. The antenna directivity estimated using beamwidth information was found to be 20.78/π dBi. From what was observed, in this work, it can be concluded that all the characteristics of the antenna are either directly or indirectly dependent on the dimensions of the antenna.

Design and Analysis of Single and Dual Fed Patch Antenna Array

Journal of emerging technologies and innovative research, 2018

In many applications it is necessary to design antennas with very high gain to meet the demands of long distance communication. The gain or directivity of single antenna is less. To increase the gain and directivity the solution is antenna array. This can be done by increasing the size of antenna. Enlarging the dimensions of single antenna often leads to more directive characteristics. Another method is increasing the dimensions of antenna without increasing the size of individual element is antenna array. It is one of the common methods for combining the radiation from a group of similar antennas in which the phenomenon of wave interference is involved. In this paper analysis of single feed and dual feed microstrip patch antenna arrays is done, and results are compared.

A NEW DUAL-POLARIZED GAP-FED PATCH ANTENNA

Progress in Electromagnetics Research C, 2010

In this paper, a new compact dual-polarized microstrip patch antenna is proposed. The patch is of rectangular shape and fed by a gap between the patch edge and a microstrip open end. Gap feeding at the edge of a rectangular patch antenna is proposed for the first time in this paper. This method of feeding occupies a negligible space compared to other feeding methods such as a quarter-wave transformer feeder, an inset feeder, a proximity coupler, and an aperture-coupled feeder. Dual-polarized radiation is realized by feeding a rectangular patch with two orthogonal gaps. First, a single-polarized patch is designed. The impedance matching property of the gap is analyzed using an equivalent circuit. Next, starting from dimensions of the single-polarized patch, a dual-polarized patch antenna is designed by optimizing the patch length and gap width. The designed antenna is fabricated and tested. The fabricated antenna has reflection coefficient less than −10 dB, port isolation greater than 30 dB, over 14.5-15.2 GHz, and a gain of 6.2 dBi at 14.9 GHz.

Development of microstrip array antenna for wide band and multiband applications

2009

The paper presents the design and development of an X-band linearly polarized microstrip array antenna. The array elements are fed by corporate feed network, which improves the impedance bandwidth of the two element rectangular microstrip array antenna (2RMSAA) by 15.38%. By increasing the array elements from two to four and eight, multiband operation can be achieved with improved impedance bandwidth. These multiband array antennas may provide an alternative to large bandwidth planar antennas in applications where large bandwidth is needed for operating at two separate transmitreceiver frequencies. When the two operating frequencies are far apart, a multiband antenna can be used to avoid the use of separate antennas. Experimental results for the array antennas in term of return loss, radiation pattern, -3dB beam width, and gain are presented.

Design of Rectangular Patch Antenna Array Using Different Feeding Technique

2017 2nd International Conference on Electrical & Electronic Engineering (ICEEE), 2017

This work analyses the performance of different feeding techniques for rectangular microstrip patch antennas used in wireless communications applications, such as in Wimax and LTE technologies. Three types of feeding arrangements are discussed here; Microstrip Line feed, Coaxial probe feed, and Aperture-coupled feed techniques. The performance of microstrip patch antenna system depends on the characteristics of the antenna element and the substrate as well as the feed configuration employed. Here the principal characteristics of interest are the antenna input impedance, mutual coupling, bandwidth, radiation pattern and return loss. In this paper, we analyze these characteristics for each feed technique, and compare them with those of the other techniques. This enables the system designer to make well informed judgement on the best feeding arrangement for his application. MATLAB has been used for the simulations and evaluations of the various performance metrics.
