provides the enhancement of gain and minimization of return loss and microstrip patch rectangular slot antenna at operating frequency of 5.8 GHz . The proposed structure will be analysed for various factors like bandwidth improvement, transmission characteristics, gain etc. Gain Enhancement of Waveguide Slot Antennas Using … illumination of the slot and enhances the efficiency in this kind of antennas. Finally, by simulation a slot antenna is excited by a quasi-TEM wave. The results indicate the high efficiency of this antenna. Keywords: Gain enhancement, quasi-TEM wave, rectangular waveguide, slot antenna. 1. Introduction Quasi-TEM mode with uniform electric field Gain enhancement and broadband RCS reduction of a May 23, 2018 · Meanwhile, a metasurface composed of an array of rectangular ring unit cells was used for enhancement of the bandwidth of a single-feed circularly polarized antenna. The designed antenna achieved return loss of 36 % and 3-dB AR bandwidth of 28.3 % [15]. Recently, Cao et al. BANDWIDTH AND GAIN ENHANCEMENT OF A SLOTTED … dielectric losses and improving the gain of the antenna, the gain of the patch antenna can be further enhanced by suppressing surface waves [5]. In this research, the effects of partial substrate removal on the performance of slotted bow-tie microstrip antenna were investigated for antenna gain enhancements. The basic idea is

Novel design concept of gain enhancement circularly polarized microstrip antennas.Measured antenna gain in this study can easily be increased by three times, as compared to the same height, substrate material, operating frequency and radiating patch shape microstrip antenna without slots in...
The slot antenna has wideband impedance, but the 3 dB axial ratio bandwidth (ARBW) is narrower compared to the impedance bandwidth (IBW). In this paper, a circularly polarized circular- slotted antenna (CSA) is proposed to enhance the ARBW and the antenna gain. A pair of asymmetrical... Antenna Gain Enhancement and Beamshaping Gain enhancement and beam shaping are illustrated by modeling the DOE lens in CST and placing it in front of different antennas. This work presents lenses for 10GHz and 40GHz horn antennas, a 3GHz slotted waveguide antenna array, and a 10GHz microstrip patch arrays. Printed Wide-Slot Antenna Design with Bandwidth and Gain… This paper presents a printed wide-slot antenna design and prototyping on available low-cost polymer resin composite material fed by a microstrip line with a rotated square slot for bandwidth enhancement and defected ground structure for gain enhancement.
