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. Gain Enhancement of Small Antenna Using 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... High gain waveguide slot array antenna for 60 gain enhancement through enlargement of the antenna size is briefly discussed in this chapter. Final conclusions are summarized in chapter 5.In order to enhance the performance of the antenna and especially its operating bandwidth some other slot shapes which are thought to have benefits...

Bandwidth and Gain Enhancement of Aperture Coupled Fed ... Bandwidth and Gain Enhancement of Aperture Coupled Fed Rectangular Patch Antenna Using Hour-Glass Shaped Slot With Back Cavity Dielectric Taufal Hidayat1, Fitri Yuli Zulkifli2, Basari3, Eko Tjipto Rahardjo4 Gain enhancement of microstrip patch antenna using Sierpinski ... Using CST Microwave studio the performance of rectangular patch antenna has been examined on proposed fractal EBG substrates. It is found that fractal EBGs are more effective in suppressing surface wave thus resulting in higher gain. The gain of rectangular patch has been improved from 6.88 to 10.67 dBi.

Wideband gain enhancement of slot antenna using one ... A quarter-wavelength-thick unprinted dielectric slab is placed above a slot antenna to achieve high gain with a large bandwidth. By optimally truncating the high-permittivity superstrate to a small area of 2.25λ0 2, 8–10 dB enhancement in the directivity of the slot is achieved over a 3 dB directivity bandwidth of 16–18%.
