Details of the proposed antenna design and role of partially reflective surface in gain enhancement of planar CPW fed UWB antenna are described6.Ghosh, A and Das, S (2014) Gain Enhancement of Slot Antenna Using Laminated Conductor Layers, International Conference on Devices, Circuits and...
ENHANCEMENT OF BANDWIDTH AND GAIN OF A … The return loss is below −10 dB from 4.45 GHz to 7.4 GHz except at 5.1GHz with a bandwidth of 48%.The antenna is thin and compact which makes it easily portable. A maximum gain of 8.77dB achieved at 4.7 GHz frequency. The VSWR parameter was found to be less than 2 within the operating frequency range. Artificial Material Integrated Ultra-wideband Tapered Slot 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 Gain Enhancement in a Microstrip Rectangular Patch …

PDF | We present in this paper a design of a high gain antenna for radar-based non-contact measurement systems in the k-band frequency. The proposed antenna consists of a slot on a multi-grooved ... Gain Enhancement of a Wide Slot Antenna Using a Second ... Gain enhancement of a wide slot antenna over a wide frequency band using a low profile, second order bandpass frequency selective surface (FSS) as a super-strate is presented in this paper. The proposed multilayered FSS with non-resonant unit cells in each layer allows in-phase transmission of waves radiated from the antenna Gain Enhancement of Rectangular Slot Microstrip Patch ... The gain of a slot antenna can be increased with the help of a single layer metamaterial superstrate. Metamaterial is used because they have negative index of refraction and it has the ability to bend light back towards the source. Keywords: zero refractive index, metamaterials, gain enhancement, patch antenna. 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%.
