A modified proximity-coupled microstrip patch antenna with broad impedance bandwidth is proposed by incorporating proximity-coupled patch antenna into the rectangular open-ended microstrip feed line on a cavity structure. First we design a proximity-coupled microstrip antenna to have a wide bandwidth in the lower band centered at 7 ㎓ using a cavity-backed ground. To broaden the bandwidth of the antenna to the upper band, we then apply a rectangular open-ended microstrip feed line, adjusting the relative position to the cavity to generate an additional resonance close to 10 ㎓. The combination of lower and upper band design results in a broadband antenna with dimensions of 30 ㎜ × 30 ㎜ × 9 ㎜ (0.9λ₀ × 0.9λ₀ × 0.27λ₀) is designed where λ₀ corresponds to the free space wavelength at a center frequency of 9 ㎓. The measurement results verify the broad impedance bandwidth (VSWR ≤ 2) of the antenna at 77% (5.6–12.6 ㎓) while the broadside gain is maintained between 6 ㏈i and 8 ㏈i within the operational broad bandwidth.
