Printed Wide-Slot Antenna Design with Bandwidth and Gain ... To increase the gain, four L-shaped slots are etched in the ground plane. The measured results show that the proposed structure retains a wide impedance bandwidth of 88.07%, which is 20% better than the reference antenna. The average gain is also increased, which is about 4.17 dBi with a stable radiation pattern in the entire operating band. A Beam Scanning Leaky-Wave Slot Antenna With Enhanced ... Abstract: In this communication, a planar beam scanning substrate integrated waveguide (SIW) slot leaky-wave antenna (LWA) is proposed for enhancing scanning range and gain flatness using a modified composite right/left-handed transmission line (CRLH TL) structure. 24 cms AERIALS - videorepeater.co.uk

MULTI-SLOTTED MICROSTRIP PATCH ANTENNA FOR WIRELESS COMMUNICATION There are several well-known methods to increase the bandwidth of patch antennas, such as the use of thick substrate, cutting a resonant slot inside the patch, the use of a low dielectric substrate, multi-resonator stack conflgurations, the use of various impedance matching and feeding techniques, and the use of slot antenna geometry [4{6]. Chapter 8 Slot Antennas - eetrend.com SLOT ANTENNAS Tapered slot antennas (TSAs) were first introduced in the late 1950s. It was then that Eberle et al9 produced a waveguide-fed, flared slot antenna for use in aircraft skins where conventional antennas could not be easily integrated. Gibson10 then developed the strip-line-fed, exponentially tapered slot antenna, which he called the ... DESIGN ANALYSIS OF HIGH GAIN WIDEBAND L-PROBE FED MICROSTRIP ... antenna designer to meet the broadband techniques [2,3]. There are numerous and well-known methods to increase the bandwidth of antennas, including increase of the substrate thickness, the use of a low dielectric substrate, the use of various impedance matching and feeding techniques, the use of multiple resonator, and the use of slot antenna Slot antenna - Wikipedia

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 Slot antenna - Wikipedia
Gain Enhancement of a Wide Slot Antenna Using a Second ...
Since the array must consist of many small antennas (sometimes thousands) to achieve high gain, phased arrays are mainly practical at the high frequency end of the radio spectrum, in the UHF and microwave bands, in which the antenna … Cantenna - Wikipedia Cantennas are typically used to increase the range (or discovery) of Wi-Fi networks.

Slot Antenna Figure 1. Rectangular Slot antenna with dimensions a and b. To gain an intuition about slot antennas, first we'll learn Babinet's principle (put into antenna terms by H. G. Booker in 1946). This principle relates the radiated fields and impedance of an aperture or slot antenna to that of the field of its dual antenna. The dual of a slot antenna would be if the conductive material and air were interchanged - that is, the … What are the best techniques to increase the gain antenna ... What are the best techniques to increase the gain antenna more than 12dBi? ... design and look into travelling wave slot antennas, then I would suggest Fermi antenna ( I had a 16dBi antenna and ...
