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.
What the Gain of an Antenna Can Tell You - and What it Can't. Gain, usually expressed in decibels, indicates how well the antenna focuses energy from a particular direction, in comparison with a standard reference antenna (an antenna with known performance, used to calibrate other or developing antenna technologies). High gain waveguide slot array antenna for 60 GHz point-to ...

1.. IntroductionA sinuous antenna is a broadband, either planar or conical, rotationally symmetric and self-complementary structure composed of multiple zigzagging arms as described in .The limits of sinuous low- and high-frequencies are determined by the outer and inner diameters of the active antenna region, respectively .Most sinuous antenna research works have been devoted to four-arm ...
