Cavity Backed Slot Antenna at 5.8 GHz Slot is cut in the top ground plane. Slot is fed using microstrip line from other side of substrate. Antenna is backed by a metallic cavity for unidirectional coverage d h Cavity Slot Feed Line W Substrate: ε r = 2.55, h = 0.787 mm, tan δ= 0.0015

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. MULTI-SLOTTED MICROSTRIP PATCH ANTENNA FOR … 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].

How can I increase the gain of a CPW fed slot antenna? How can I increase the gain of a CPW fed slot antenna? The antenna is a spiral slot fed by a CPW. It has good impedance matching but its gain is 0 dBi. ... 3D structure might help not only to ... ENHANCEMENT OF BANDWIDTH AND GAIN OF A RECTANGULAR MICROSTRIP ... Patch Antenna with enhanced gain. The aim of the project is to design a rectangular Microstrip Patch Antenna with enhanced gain and bandwidth and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative Dielectric constant (ε r), substrate thickness on antenna gain and bandwidth. How to increase antenna gain - Quora Start with a point source that with radiates/receives power equally in all directions and modify that design so that the gain increases in some directions and decreases in others. You cannot increase gain in all directions. Highly directional antennas provide high gain in one direction with highly attenuating signals in other directions. Slot Antenna

A gain-enhanced low profile substrate integrated waveguide (SIW) cavity-backed slot antenna is presented in this paper. By etching three parallel transverse slots on the center and both edges of the rectangular SIW cavity as the radiating elements, higher resonance mode of TE 410 can be excited to achieve gain enhancement.
