In today’s world, the requirement for lower-weight, low-cost, low-profile, and effective-use transmitters is growing by the day. For addressing these parameters in a variety of applications, microstrip patch antennas are more popular than other antennas. The main issue with these types of microstrip patch antennas is that they have a high return loss, VSWR, and bandwidth, but these issues can be rectified utilizing a design technique. The method of design was to use mirror image layouts, which was a simple and easy way to improve performance. The efficiency of a simple patch cannot be influenced by any single structure that lacks a mirror reflection. In this study, the two +-shaped constructions are used, and the results are in good agreement. In today’s world, these antennas have a variety of uses, including WLAN and s band applications. In the future, various frameworks will be used to improve the results that have been produced thus far.

This paper presents novel low-cost single- and dual-band microstrip patch antennas. The proposed antennas are realized on a square microstrip patch etched symmetrically with four slots. The antenna is designed to have low cost and reduced size to use in Internet of things (IoT) applications. The antennas provide a reconfigurable architecture that allows operation in different wireless communication bands. The proposed structure can be adjusted to operate either in single band or in dual-band operation. Two prototypes are implemented and evaluated. The first structure works at a single resonance frequency (f1 = 2.4 GHz); however, the second configuration works at two resonance frequencies (f1 = 2.4 GHz and f2 = 2.8 GHz) within the same size. These antennas use a low-cost FR-4 dielectric substrate. The 2.4 GHz is allotted for the industrial, scientific, and medical (ISM) band, and the 2.8 GHz is allocated to verify the concept and can be adjusted to meet the user’s requirements. The measurement of the fabricated antennas closely matches the simulated results.

Conventional Microstrip patches are in small in size, but their gain is quite low for most applications. Long-distance communication requires high gain antennas. For conventional applications that require high gain mostly depends on parabolic antennas and arrays. Manufacturing parabolic antennas became complex at high frequencies because of its bent geometry. Microstrip Patch Antennas are low profile, low cost, they come with ease of fabrication and results in high beam scan width and high gain when they were used as an array configuration. In this paper, square and circular shaped Microstrip patch antennas are excited with inset feed are analyzed to determine which shape of antenna works well at the Ku (12-18GHz) Range of Frequency. Return loss, VSWR, Gain, and Directivity parameters are considered to analyze the above configurations. CST studio suite tool was used to simulate the configurations.

ABSTRACTSemi-insulating (SI) silicon carbide (SiC) was evaluated as a candidate material for dielectric substrate for patch antennas suitable for monolithic antenna integration on a SiC semiconductor chip. Computer simulations of the return loss were conducted to design microstrip patch antennas operating at 10 GHz. The antennas were fabricated using SI 4H-SiC substrates, with Ti-Pt-Au stacks for ground planes and patches. A good agreement between the experimental results and simulation was obtained. The radiation performance of the designed SiC based patch antennas was as good as that normally achieved from antennas fabricated using conventional RF materials such as FR4 and Rogers. The antennas had the gain around 2 dBi at 10 GHz, which is consistent with the conventional antennas of a similar size.

Modern communication system is based on wideband communication. A wideband antenna is designed in such a way that it will receive a wide range of frequencies. Microwave frequency spectrum is classified as ranging from 1GHz to 100GHz and this range is divided into a number of frequency bands. These bands are defined as L Band, S Band, C Band, X Band etc. To fulfil the demands of many users patch antenna is designed in these bands. Among different types of antenna, Microstrip Patch Antenna is most popular in wireless communication system. Microstrip patch Antennas have many advantages over other familiar antennas because microstrip patch antennas are of low profile, low cost, low volume, light weight. Low efficiency, low gain and narrow bandwidth of patch antenna create major challenge to a designer. Slots are created on patch for preparing antenna forwideband applications. In this paper, we have surveyed upon various types of Microstrip Patch Antenna, feeding techniques, design equation Substrate Characteristics, Simulation tools etc.

Selecting an appropriate substrate material for the design of microstrip patch antenna for various applications is a very important step in antenna design. This paper presents a work of various substrates materials used for the design of low cost inset feed rectangular microstrip antenna for WLAN, WiMax, LTE, C-band and X-band applications. The substrates used are FR-4 epoxy, foam, polyethylene terephthalate (PET) and polydimethylsiloxane (PDMS). The antennas were designed, optimized and simulated using HFSS 15.0. Return loss, voltage standing wave ratio and gain analysis is carried out for these antennas. The measurement of reflection coefficient of the fabricated antennas is done using Agilent PNA-L series vector network analyzer. The simulated and measured results are well in agreement. The analysis show that antenna with foam substrate offers the lowest return loss of - 41.28 dB. Larger bandwidth and gain of 4.38 dB is observed with PET substrate.

In this study, we developed an analytical model of slot-loaded rectangular microstrip patch antennas based on the simulation results by varying slot parameters. The dominant resonant frequency predicted by such a model is in strong agreement with the experimental results measured at several locations of slot-loaded rectangular microstrip patch antennas. The model enables a reliable and quick computation of the resonant frequency, which generally follows a harmonic behavior that nearly resembles the resonant frequency of a microstrip antenna without a slot, which can be related to a small change in the impedance caused by the slot position. Results showed a good agreement between simulations and measurements for all the slot positions. Mathematical analytic functions to describe the changes in specific characteristic parameters of the slot-loaded rectangular microstrip patch antennas are also included.

Microstrip patch antennas are the handiest antennas for the present trend of applications in communications. The well-known beneficial mechanical characteristics (low profile, light weight, planar but conformal to non-planar structures, easy to fabricate), flexibility in terms of electromagnetic parameters like radiation pattern, gain, impedance, polarization and low cost are the key features for the success of such antennas. High efficiency antennas are essential to cater the requirements of various military oriented space vehicles like spacecraft, aircraft, satellite and missile applications where dimensions of installation are important as size, weight, performance, ease of installation and easy integration to the circuit. Microstrip antenna array are most apt for such applications, but the limitation of such antennas are gain and the bandwidth. The order of gain is low for patch antenna which is generally in the choice of 1-2dB.To increase gain and bandwidth factors the utilization of material with low dielectric constant having greater thickness is employed. However, this generates surface waves. So, proper thickness of substrate is selected. In this paper, microstrip patch having pentagon shape uses probe feed technique for various substrate materials such as Roger’s RT/Duroid 5880 (tm), Roger’s RO4003 (tm) and FR4 epoxy. The results of the three substrate designs are acquired for the resonant frequencies 6.5 GHz, 6.6 GHz, and 6.7 GHz respectively. The whole analysis is carried out using Ansoft HFSS software version 17.0. The characteristics like bandwidth, amplification factor (gain), return loss and radiation patterns of the different antenna are assessed, related and the same are presented at the end.
