The measurement results alongside the simulation data for our antenna's performance are shown here. The measured S11 values, as displayed in Figure 5, indicate a slight deviation from the simulation at lower frequencies. Our 38 GHz slot chip antenna design maintains a reflection coefficient well below the -10dB threshold across a bandwidth from 18.8 to 32.5 GHz. Despite its compact footprint of 1150 by 1000 square micrometers, it achieves an effective reflection band, thanks to the ground layer M1 which employs the slot effect to enhance gain. While direct measurement of the gain for a mmW patch antenna is currently beyond our instrumentation's capabilities, simulations suggest a gain of approximately -7dBi, as demonstrated in Figure 6. This simulated gain reaffirms the antenna's suitability for advanced millimeter-wave applications. |
