Abstract :
A novel compact slot antenna fed by the conductor-backed coplanar waveguide (CBCPW) is proposed. The antenna is composed of a CBCPW-fed slot dipole and an additional arc-slot in front of the dipole. Compared to the CBCPW-fed slot dipole without the arc-slot, the antenna gain is improved significantly. The antenna occupies a small area and uses only one layer of dielectric substrate and a single feed without any via holes. The impedance bandwidth is 7.2 % and the highest in-band antenna gain is 3.4 dBi.
