1. A millimeter-wave end-fire magneto-electric dipole antenna comprising:
a first substrate having a first substrate thickness;
a second substrate placed on the first substrate and having a second substrate thickness different from the first substrate thickness;
an asymmetric substrate integrated coaxial line (ASICL) feed, comprising:
a conductive signal line formed on an upper surface of the first substrate and placed between the first substrate and the second substrate; and
two waveguiding walls positioned along and at both sides of the conductive signal line respectively and extending substantially perpendicularly through the first and second substrates;
a probe, comprising:
a lower strip portion deposited on a lower surface of the first substrate;
a middle strip portion deposited on an upper surface of the first substrate and connected to an extension from the conductive signal line;
an upper strip portion deposited on an upper surface of the second substrate;
a first connecting via extending substantively perpendicularly through the first and second substrates for connecting the lower strip portion and the upper strip portion; and
a second connecting via extending substantively perpendicularly through the first substrate for connecting the lower strip portion and the middle strip portion.
