摘要：In this communication, a novel transverse slot array with standing-wave excitation using substrate-integrated coaxial line (SICL) technique is proposed. The transverse series slots are arranged with a uniform spacing of one guided wavelength and centered over the inner strip of the SICL. A 5× 1 element linear subarray is designed with suppressed sidelobe levels (SLLs). A tapering power divider is then adopted to feed eight such subarrays and finally a 5× 8,2 -D array is fabricated and tested for demonstration. A -10 dB impedance bandwidth (BW) from 33.87 to 35.10 GHz (3.57% at 34.5 GHz) is measured out with a peak broadside gain of 18.82 dBi. The E-plane and H-plane SLLs are -18.4 and -19.2 dB, respectively. Agreement between theory and experiment has been found to be good for both the linear array and the proposed antenna. © 1963-2012 IEEE.
