Design and Analysis of Linear Tapered Slot Antenna for Super High Frequency Applications

In this paper, the proposed LTSA (Linear Tapered Slot Antenna) is assisted with an air cavity and fabricated using LTCC substrate (Low Temperature Cofired Ceramic). The LTSA antennas are widely used in multimedia applications, which require larger bandwidth and high gain. If thelinear slot antenna is designed on low temperature cofiredceramic board, because of its thickness and high dielectric constant, the gain and radiation property is infected critically. By selecting air cavity in the rear end of low temperature cofired ceramic substrate, much gain and good end fire radiation pattern can be acquired. Typically, this antenna has wide bandwidth (45 GHz to 75 GHz) and 4.9 to 6.9 dB gain. The proposed the 3D LTCC modules can be used for wide variety of super high frequency applications.
