Gain and Bandwidth Enhancement Techniques in Microstrip Patch Antennas - A Review
Today antenna designers are paying more focus on microstrip patch antennas, because of its numerous advantages in field of communication, such as high reliability, light weight, ease of fabrication etc. But despite of its bountiful advantages, patch antennas also experience some drawbacks viz low gain and narrow bandwidth. These drawbacks can be overcome by taking care of some parameters in the...
متن کاملBandwidth and Gain Enhancement of Microstrip Patch Antennas Using Reflective Metasurface
Bandwidth and gain enhancement of microstrip patch antennas (MPAs) is proposed using reflective metasurface (RMS) as a superstrate. Two different types of the RMS, namelythe double split-ring resonator (DSR) and double closed-ring resonator (DCR) are separately investigated. The two antenna prototypes were manufactured, measured and compared. The experimental results confirm that the RMS loaded...
متن کاملBandwidth Enhancement for Microstrip Antenna in Wireless Applications
Antenna is a vital component in wireless application systems. The microstrip antenna can be used for wireless applications as it has features such as light weight, easily mounted and it is easy to mass produce. Although there are many features that suits well for microstrip antenna to be deployed for wireless applications, there is a very serious limitation where it has a very narrow bandwidth....
متن کاملH-U-E Shaped Slotted Microstrip Antenna for Bandwidth Enhancement
An H-U-E shaped slotted microstrip antenna with improved bandwidth is presented in this paper. The antenna resonates in the frequency range of (2.0–6.3) GHz with the center frequency of 4.2 GHz. The proposed antenna provides return loss approximately -30 dB. The antenna is fed with coaxial feeding yields an impedance bandwidth of 103.6% and VSWR of less than 1.07. The proposed antenna is simula...
متن کاملMultilayer Microstrip Antenna Quality Factor Optimization for Bandwidth Enhancement
The impedance bandwidth, one of the important characteristics of microstrip patch antennas, can be significantly improved by using a multilayer dielectric configuration. In this paper the focus is on bandwidth enhancement technique of a multilayer patch antenna for X-band applications. In order to enhance the bandwidth, antenna losses are contained by controlling those quality factors which can...
