Abstract :
We propose a millimeter-wave antenna that can be assembled using several printed boards. A post-wall horn antenna structure and tapered slots are responsible for the narrowing of the radiation pattern in the H-plane and the E-plane, respectively. Further, to improve the matching with free space and obtain a better radiation pattern, a dielectric projection that tapers is attached to the antenna tip. Numerical results show that a working gain of ¿17 dBi can be obtained in the frequency range 57-66 GHz.
