摘要
Tapered endfire slotline antennas, of the BLTSA type, have been fabricated on 1.7 muM thin SiO2/Si3N4 dielectric membranes. Antenna patterns of the E-, H-, and D-planes have been measured at 802 GHz. The -10 dB beamwidths were found to be approximately 40-degrees in all planes, with side lobe levels below -11 dB (-19 dB in the E-plane). The cross-polarized peaks in the D-plane are 8 dB below the co-polarized peak. A theoretical model for calculating the E- and H- plane patterns of tapered slotline antenna has been extended to include the co- and cross-polarized D-planes. Measured and calculated patterns show good agreement.
