High-gain antennas have various applications such as in satellite platforms, radar systems, routers, and repeater systems.In this paper, we propose a novel enhanced-gain planar slot antenna backed by an SIW cavity for 2.4 GHz wireless local area network (WLAN) applications. Broadband and high-gain microstrip slot antenna INTRODUCTIONMicrostrip slot antennas are widely used for military and commer-cial applications due to their promising features such as lightweight, small sizeTherefore, a metallicreector or an enclosed cavity behind the slot should be used toreduce the back radiation and enhance the antenna gain. Will a high gain antenna actually suit your purpose? High gain antennas take all of the inputted signal and transmit it along the horizontal plane in a tight, narrow beam. PROS : Yes, the signal does travel further.A medium gain antenna redistributes some of the signal that would have been sent vertically up and down and pushes it along the horizontal plane. Antenna Gain | Is a High Gain Antenna Advantageous? Antenna Gain is sometimes discussed as a function of angle. In this case, we are essentially plotting the radiation pattern, where the units (or magnitude ofThe gain of a real antenna can be as high as 40-50 dB for very large dish antennas (although this is rare). Directivity can be as low as 1.76 dB for a...

The Steatite family of sinuous antennas simultaneously handle signals of any two orthogonal linear polarisations and simultaneous left and right-handed circular polarisations dependent on antenna design.. This provides intercept opportunities for a wide range of arbitrarily polarised signals, from devices also giving a wide bandwidth and broad beamwidth. A ultra wide band sinuous antenna design with enhanced ... Simulated results shows the high degree of polarization purity attained. 1. Introduction The sinuous antenna, introduced by DuHamel in 1987 [1], has been used since then in many ultrawideband (UWB) systems, both in its dipole version and in its slot version, with two or four arms [2–5]. Sinuous antennas are excellent for UWB applications and
