  14. NORTH DAKOTA STATE UNIVERSITY Proposed Design Guidelines b = 5.00 mm, s = 61.00 mm, ws= 21.37 mm, Ls= 43.40 mm, r= 41.80 mm, d = 2.00 mm, g = 0.63 mm, m = 1.79 mm, n = 0.71 mm, Lf= 2.77 mm, P = 43.5 mm and Q = 160.5 mm. Changes in Geometry Changed Parameters: ws , Ls , r , one at a time APPLIED ELECTROMAGNETICS LAB

  15. NORTH DAKOTA STATE UNIVERSITY Proposed Design Guidelines Effect of changes in ws(slot height) Observation:S11 can be improvised by increasing the dimension of the radiating slot of the antenna. Advantage:A better S11 can be obtained without changing the overall dimension of the antenna APPLIED ELECTROMAGNETICS LAB

  16. NORTH DAKOTA STATE UNIVERSITY Proposed Design Guidelines Effect of changes in Ls(slot width) Observation:A second resonance point at 2.3 GHz has been found without any changes of the default characteristics of the antenna Advantage:Dual-band characteristics can be achieved without changing the overall dimension of the antenna APPLIED ELECTROMAGNETICS LAB

  17. NORTH DAKOTA STATE UNIVERSITY Proposed Design Guidelines Effect of changes in r (size of the dipole) Observation:The resonance frequency can be changed by decreasing the size of the dipole exciting the radiating slot of the antenna Advantage:The overall radiating frequency can be decreased without changing the overall dimension of the antenna APPLIED ELECTROMAGNETICS LAB

  18. NORTH DAKOTA STATE UNIVERSITY Conclusion • Introduction and Background on the CPW-fed slot antenna has been discussed. • Conformal CPW-fed slot antenna array has been introduced. • Measurement and Simulation Results are compared for different bend angles of the surface of the antenna. • New design guidelines have been proposed for the improvisation of the antenna characteristics.
