Gain Enhancement of a Wide Slot Antenna Using a Second-Order Bandpass Frequency Selective Surface ... a reasonable increase in the antenna size was required due The Basics of Patch Antennas, Updated - Orban Microwave The Basics of Patch Antennas, ... A thicker substrate increases the gain to some extent, ... These slots typically have a directivity of 2 to 3 dB compared
A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna.The shape and size of the slot, as well as the driving frequency, determine the radiation pattern.Often the radio waves are provided by a waveguide ...

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
