- Abstract
A metamaterials slabs covered antipodal Vivaldi antenna (MSCAVA) is proposed herein to improve directivity and gain. The proposed metamaterials slabs have a higher effective permittivity than the substrate. The design process of proposed MSCAVA is presented, along with the comparison with other existing works. The simulated and measured results show that the −10 dB bandwidth of the proposed antenna is 1.5 to 8 GHz while the E‐planes' and H‐planes' half‐power beamwidth have been effectively reduced. The maximum gain is 16.4 dBi at 8 GHz. Owing to those good properties, the proposed MSCAVA could be used in short‐pulse ground penetrating radar and other situations where need high gain and directivity.
