Dual-band one-sided directional slot array antenna for 10GHz and 24GHz application

This paper presents a design of one-sided directional dual band slot array antenna for both 10GHz and 24GHz application. The antenna element is composed of a top metal, a dielectric substrate, and a bottom metal layer. This antenna is divided into a part corresponding to the upper X-band 2 array and to the lower K-band 4 array antenna. The antenna element is connected to the coplanar waveguide (CPW) feed line. From the simulation and measurement result of the return loss and antenna gain are presented in this paper. The peak gain of proposed antenna is 6.32 dBi at 9.6 GHz and 10.40 dBi at 24 GHz.
