A circularly polarized, dual-frequency, slotted square patch with probe feeding mechanism is reported
to operate as the telemetry, telecommand and control (TT&C) antenna for satellite spacecrafts at 2.25
GHz and 3.0 GHz [15]. A compact patch design for circular polarization application based on third
iteration minkowski-like pre fractal geometry to be used in dual band application was reported by Ali
Jalal [16]. Two short-circuited microstrip patch antennas can radiate at dual frequencies was reported
by Roy and Thomos [17]. A trade-off is taken among these techniques and optimized geometries are
developed in this study. This paper demonstrates a technique to achieve both bandwidth enhancement
and reduction of antenna structural profile. It is achieved by a novel design of wide slots along the
radiating edges of the microstrip patch fabricated on low cost FR4 dielectric material.
