Abstract
A new array formation method for millimeter-wave (mm-wave) transverse slot scanning array antenna is proposed, which can effectively solve the grating lobes problem caused by the traditional array formation method. To verify the array formation method, a mm-wave scanning array antenna at 30GHz is designed, which consists of a traditional substrate integrated waveguide (SIW) 4 x 4 Butler Matrix (BM) feed network and 16 transverse slot elements. The distance between adjacent transverse slot elements is equal to half waveguide wavelength, and the transverse slot array antenna uses the metal cylinder matching method to improve the effective bandwidth of the array antenna, a −10dB impedance bandwidth (BW) of scanning array antenna from 28.9 to 31.04 GHz is simulated. The peak broadside gain of the array antenna is 13.7dB. This type of transverse slot scanning array antenna will have many applications in the future 5G mm-wave band.
