Design and Enhancement of Gain & Bandwidth of... -… Microstrip antennas are strongly used in wireless communication applications. This paper proposed a rectangular patch antenna loaded with a semi-circularThis paper also describes the increment in bandwidth and gain of rectangular microstrip patch antenna with the slot. Microstrip patch antenna is... Gain Enhancement in a Microstrip Rectangular Patch … The improvement in the radiation gain characteristic of a conventional RMPA upon the use of alphabetical slots has been investigated. The RMPA design has been built using a 58mm x 80 mm Flame Retardant-4 Epoxy substrate that is 1.6 mm thick and has a dielectric constant of 4.4.
Gain of the antenna indicates the antenna efficiency and its direc-tion capabilities. The gain is usually measured at an angle where the maximum radiation occurs.The gain of circular ground plane antenna with slots is high than the rectangular ground plane antenna, from which we can say that...
An important feature of the proposed antenna design is the stimulus of impedance matching caused by the coupling effects between wide slot and feed length and width. For this reason, the effect of the length , 28.5, 29, 29.5, and 30 mm on the performance of the proposed design is investigated and depicted in Figure 6. Gain-enhanced SIW cavity-backed slot antenna by using ... Furthermore, many gain enhancement methods have been taken into antenna designs. In , by etching two parallel slots at cavity edges as radiating elements to excite TE 120 resonance only, the antenna gain has been improved to about 7.1 dBi. Bandwidth and Gain Enhancement Of Proximity Coupled ... high gain antenna. Some techniques can be used to achieve high gain antenna. Some paper have been proposed to enhanced bandwidth and gain of a single element antenna, one of that is by using aperture coupled patch with hour glass slot [1]. But these methods do not achieve optimum performance for bandwidth and gain of single element.

Gain Enhancement in a Microstrip Rectangular Patch Antenna Using Alphabetical Slots Deepanshu Kaushal and T Shanmuganantham Department of Electronics Engineering, Pondicherry Central University, Pondicherry, India shanmugananthamster@gmail.com _____ ABSTRACT The improvement in the radiation gain characteristic of a conventional RMPA upon the use of alphabetical slots has been investigated.
Microsoft Word - str_0046-0052 Abstract. A novel design of high-gain and low-scattering [5], the AMC is loaded around the rectangular microstrip waveguide slot antenna is proposed in this paper.
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.
