Step 4: Calculation of the length extension (L): Step 3: Calculation of the Effective length (Leff ): The design of the proposed microstrip patch antenna was modeled using the classical equations. The design of the proposed antenna is shown in Fig.1 and Fig 2. It is very easy to analyze using both the transmission-line and cavity models, which are most accurate for thin substrates. The rectangular patch is by far the most widely used configuration. This proposed antenna has rectangular patch used. In some applications, such as in government security systems, narrow bandwidths are desirable. However, they suffer from low gain, narrow bandwidth, low efficiency, and low power handling capability. Microstrip antennas (MSA) offer many attractive features such as low weight, small size, ease of fabrication, ease of integration with Microwave Integrated Circuits (MIC) and can be made conformal to host surface. However, practical antennas were developed by Munson - and Howell in the 1970s. Deschamps first proposed the concept of the MSA in 1953. This Microstrip antenna have been one of the most innovative topics in antenna theory and design in recent years, and are increasingly finding application in a wide range of modern microwave systems. Where, c = 3 x 108 m/s, r=2.1, fr = Designed Frequency Step 2: Calculation of Effective dielectric constant (reff ): KeywordsCST Microwave Studio, Microstrip Patch Antenna, Ku band. At resonant frequency 12.54GHz the verify and tested result on CST Microwave Studio by CST STUDIO SUIT are Return loss = -26.5578 dB, Voltage Standing Wave Ratio = 1.0986392, Gain = 6.906dB, Directivity = 6.976dBi, Bandwidth = 4.1553GHz (33.14%) and Efficiency = 98.99%, all results are shown in simulation results.
