✦ Synopsis

An amplifier-type acti¨e microstrip antenna, as a transmitting antenna, consisting of a passi¨e broadband slotted triangular microstrip antenna and a coplanar amplifier circuitry for enhanced gain and bandwidth, is demonstrated. The acti¨e microstrip antenna studied ( here is printed on an inexpensi¨e FR4 substrate relati¨e permitti¨ity 4.4, ) thickness 1.6 mm , and shows an extra output gain of 6 dB and a 9.3% bandwidth in the 1.8 GHz band, which is about two times that of the passi¨e broadband slotted triagular microstrip antenna or six times that of the passi¨e con¨entional unslotted triangular microstrip antenna. Details of the antenna design and experimental results are presented.

A new design of a reduced-size triangular microstrip antenna fed using an inset microstrip line is presented. The antenna size reduction is achie¨ed by loading a chip resistor at the triangle tip of the patch. With an increasing resistance of the loaded chip resistor, the antenna bandwidth is signif
