Abstract: Here we are presenting the design of microstrip patch antenna with rectangular patch for L Band applications. We measure experimentally various parameters of rectangular patch antenna such as return loss, VSWR, %BW, gain, antenna efficiency and directivity. Now a day bandwidth of microstrip patch antenna is main concern. A lots of method such as slotting like E-slot, U-slot, L-slot, I-slot and many are carrying out in order to increase the percentage bandwidth of patch antenna, but these methods are complicated to design. Therefore we design a rectangular patch antenna using computer software Zealand IE3D v15, which improves the percentage bandwidth of proposed antenna by 28.95%. The proposed antenna covers the L Band, has many applications such as mobile services, satellite navigation, aircraft surveillance and digital broadcasting.
