摘要：
A numerical simulation and an experimental implementation Of a cross-shaped, microstripline-fed, printed, four-element slot antenna array are presented in this article. The proposed antenna, with a relative permittivity of 4.3 and a thickness of 1.0 mm, is analyzed by the finite-difference time-domain (FDTD) method. The dependences of the design parameters l(d), l(u) and offset on the bandwidth characteristics are investigated. The measured bandwidth of a four-element slot antenna array is 1.4467 to 2.5979 GHz, which is approximately 57 percent for S-11 less than or equal to -10 dB. The cross-polarization level is less than -25 dB. The measured gain of a four-element slot antenna array is more than 7 dBi in the usable frequency band.
