Gain Enhancement of Waveguide Slot Antennas Using Quasi ... To show the efficiency improvement in slot antennas, a leaky-wave antenna with 10 periodic transverse slot elements on Rogers RO5850 substrate with a permittivity of 2.2 and loss-tangent of 0.0009 is simulated. Fig. 7 depicts the proposed antenna structure. The dimensions of a unit cell of the antenna are given in Fig. 8. Fig. 3. Gain and Bandwidth Enhancement of Rectangular Patch ... Gain and Bandwidth Enhancement of Rectangular Patch Antenna with Trapezoidal Slot for Wi-Max Applications written by Gitansh Gulati, Dheeraj Bhardwaj, Manan Dixit published on 2014/11/24 with reference data and citations Gain enhancement and broadband RCS reduction of a ... 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.
Gain Enhancement of Elliptical Monopole Antenna using ...
grated TSA with SRR slot is presented to enhance gain with band notch characteristics. The artificial material is integrated in tapered slot area of the basic TSA and the peak gain of antenna is increased from 9.4 to 10.9 dBi at 10 GHz. The SRR is etched near the excitation area or input aperture of the antenna which is responsible for notch 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. 2D Gain Enhancement Based on Single-Layer SIW Corrugated ... Novel slot-array-based SIW corrugated technique is demonstrated to achieve 2D gain enhancement, namely, sharpening the beamwidths in both E-plane and H-plane. Compared to other metallic corrugated methods to realize 2D gain enhancement, the proposed design, with SIW grooves to reduce the beamwidth ... A Review on Gain & Bandwidth Enhancement Techniques of ...

The designed antenna exhibits wideband. frequencies with VSWR < 2.2. Bandwidth enhancement of rectangular microstrip patch antenna using slots.percentage bandwidth increased to 91% with respect to the centre frequency 3.7GHz.the gain of the antenna. with two slots is 2.5dB where as for... Gain Enhancement of Slot Antenna Using Grooved Structure The proposed antenna consists of a slot antenna on a grooved metal structure with a single frequency selective surface. In addition to a high- gain characteristic, a reduced size is strongly required for easy embedding. These features are the main objectives of this antenna design.
