Abstract :
In this paper, one linear tapered slot antenna (LTSA), backed with an air cavity, is proposed and fabricated on low temperature cofired ceramic (LTCC) substrate. Conventionally, when LTSA is designed on LTCC board, due to its high dielectric constant and thickness, the gain and radiation property is degraded seriously. Therefore in this paper. by adopting an air cavity in the back side of the LTCC substrate, high gain and good endfire radiation pattern can be obtained. In particular, this antenna has broad bandwidth (about from 45 GHz to 75 GHz) and high gain (4.9-6.9 dB) property. This antenna can be used for a variety of millimeter-wave applications due to its easy integrability with 3D LTCC modules.
