Microstrip-fed 3D-printed H-sectorial horn phased array

# metadata.dc.description.abstract[].value
3D-printed phased array consisting of four H-Sectorial horn antennas of 200 g weightwith an ultra-wideband rectangular-waveguide-to-microstrip-line transition operating over the wholeLMDS and K bands (24.25–29.5 GHz) is presented. The transition is based on exciting three overlappedtransversal patches that radiate into the waveguide. The transition provides very low insertion losses,ranging from 0.30 dB to 0.67 dB over the whole band of operation (23.5–30.4 GHz). The measuredfractional bandwidth of the phased array including the transition was 20.8% (24.75–30.3 GHz). Theantenna was measured for six different scanning angles corresponding to six different progressivephases a, ranging from 0 to 140 at the central frequency band of operation of 26.5 GHz. Themaximum gain was found in the broadside direction a = 0, with 15.2 dB and efficiency h = 78.5%,while the minimum was found for a = 140, with 13.7 dB and h = 91.2%.
