A CPW-fed inductively coupled modified bow-tie slot antenna

A CPW-fed inductively coupled bow-tie slot antenna is introduced. Several geometric parameters of the antenna were varied to observe the impedance matching between the CPW-feed and the antenna. The inductively coupled CPW feeding mechanism makes the concept suitable for array applications. The bandwidth reduction for an inductively coupled straight-dipole slot is overcome by utilizing an inductively coupled bow-tie slot. Antenna models for operation at 2.45 and 5.5 GHz were constructed and return loss and radiation pattern results were obtained. The proposed antenna provides bandwidths of 8% and 13% at 2.45 and 5.5 GHz, respectively.
