Abstract
This article presents a coplanar waveguide (CPW) antenna with a trident shape for ultra-wideband (UWB) applications. First, a basic shape of trident CPW antenna is proposed to excite three resonant modes. The three resonances create a wide operating band but cannot cover the entire UWB band. To increase the impedance matching, the parameters of the proposed antenna are modified, which include adding two strips on the two outer arms and truncating two slots on the bottom of the middle arm. The ground plane of the proposed design is also modified to obtain better impedance matching. Finally, the 10 dB return loss that covers the UWB applications is accomplished. Besides, the dimensions of the proposed design occupy a small area of 32 mm × 17 mm × 0.8 mm with planar structure, which is convenient to apply in wireless devices. This article will provide the experimental measurements of return loss, radiation patterns.
