Abstract
A novel fractal patterned iris loaded cross dipole slot antenna along the broad wall of a rectangular waveguide at X-band is proposed with wideband operation. Tapering the junction of the cross slots results in wide impedance matching. Bandwidth enhancement better than 2 GHz is achieved with optimisation of iris depth and inclusion of a second iteration slot in the vicinity of the primary cross slot. Peak realised gain remains around 7 dBi over the operational bandwidth.
