Gain Enhancement of 60-GHz Antipodal Tapered Slot Antenna ... Abstract: A zero-index metamaterial (ZIM) structure is proposed for the gain enhancement of an antipodal tapered slot antenna (ATSA) at 60-GHz bands. The single ATSA loaded with the proposed ZIM cells exhibits a gain enhancement of up to 2.6 dB in the frequency band of 57-66 GHz. Gain enhancement of annular slot antennas - IET Journals ...

BANDWIDTH AND GAIN ENHANCEMENT OF A SLOTTED BOWTIE ANTENNA USING ... Printed slot antennas offer an attractive solution to compact, conformal, and low-cost designs of many wireless application systems [1] due to small size, light weight, low cost, good performance, and low profile [2]. Gain Enhancement of 60-GHz Antipodal Tapered Slot Antenna Using Zero ...
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.
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.
Slotted UWB Antenna for Bandwidth and Gain Enhancement
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%.
