Abstract
ABSTRACTIn this paper, a dual-band reconfigurable substrate-integrated waveguide (SIW) cavity-backed slot antenna 1 × 8 linear array is presented with dual states. The proposed SIW antenna array combines the features of the conventional metalized cavity-backed patch arrays such as surface wave suppression, high efficiency with low-manufacturing cost. The basic element has been designed, fabricated and the performance has been verified in the outdoor antenna test range. Here, PIN diodes have been used as a switching device to achieve the reconfigurability with dual-band operation. A corporate feed network has been designed and integrated with the antenna to make it as a linear array.
