“…Many approaches have been studied for miniaturizing MSA, the methods for miniaturization includes half-cutting method [7], using slits [8], using fractal geometry and partial cutting method [9], using shorting post and defected ground structure (DGS) [10]. These methods have significantly contributed to developing compact antennas.…”

A Coplanar Waveguide (CPW) fed antenna with a T-type slot and Partially Reflecting Surface (PRS) for gain, bandwidth, and efficiency improvement is presented. The antenna is miniaturized to get size reduction of 46.50%. The miniaturized antenna covers frequencies in C band. The presented antenna structure is easy to design and has size of 0.682λ g × 0.99λ g × 0.053λ g . The PRS with parasitic patches is placed on top of the antenna at a distance of 0.25λ g . The presented antenna design has a bandwidth of 4.42 GHz (Antenna 1) and 3.87 GHz (Antenna 2) with a percentage bandwidth of 75.81% and 59.58% respectively having average radiation efficiency above 90%. The gains obtained are 7.03 dBi and 6.12 dBi for Antenna 1 and Antenna 2. The gain has < 3 dB variation over the complete band. The obtained results support the design and make the antenna suitable for C band applications.
