Abstract :
The Search and Rescue Transponders are
used to search for the lost ship and aircraft. The
transponder antenna resonates at the frequency of 9
GHz. The design is considered using FR4 (Flame
Retardant) substrate of dielectric constant 4.4 and loss
tangent 0.0019. A micro strip line fed rectangular patch
antenna is designed in such a way that it resonates at 9
GHz. The return loss and gain for the designs are, Single
Element Design: Return Loss is -24.291 dB, Gain Total is
5.9083 dB, 1*2 Array Design: Return Loss is -19.3635
dB, Gain Total is 8.5915 dB, 1*4 Array Design: Return
Loss is -34.4773 dB, Gain Total is 9.4879 dB. Other
antenna parameters such as VSWR, Radiation
Efficiency, Gain 2D, Specific Absorption Rate are
observed. The antenna structure is simple, flat and
straightforward. The design can be embedded easily in
Search and Rescue Transponder Transmitter because it
is geometrically small. The simulation and analysis were
done using High Frequency Structure Simulator
(HFSS).
