Abstract
A novel air gap coupled microstrip patch antenna is proposed for K/Ka band wireless applications. The antenna consists of defected ground structure and three-layer stacking of two FR4-epoxy and one air gap with two rectangular patches layered vertically with L-shaped slot. The dimensions of the antenna are 20 × 20 × 4 mm3. The proposed antenna operates in the frequency ranges of 16.89–33.89 GHz which covers the total K-band (18–26.5 GHz) and partial Ka band (26.5–40 GHz). The designed antenna is simulated by using HFSS EM simulator. The simulation result shows the proposed antenna gain of 9.34 dB and radiation efficiency of 76%.
