Width discontinuity, electrically small microstripantenna, efficiency.
When width discontinuities are introduced in a
conventional rectangular microstrip antenna, the antenna
size is substantially reduced. However the antenna
efficiency decreases as the antenna becomes small. In
this paper the antenna efficiency of the electrically small
antenna is investigated and a microstrip structure that
shows improved efficiency is introduced.
