Study and design of multiband antenna with V and U slot on patch for wireless application

A compact Multiband Microstrip Patch Antenna with V cut connected to U slot on patch for super high frequencies (SHF) in C band and X band applications is proposed. The proposed antenna fabricated on a FR-4 substrate with dimensions 40 mm (L) × 40 mm (W) × 1.6 mm (h), relative permittivity εr =4.4 and loss tangent δ = 0.025. The proposed antenna is designed by etching V cut connected to U slot on a rectangular patch(0.2473λ×0.3092λ) with inset feed. CST microwave studio suite software used to simulate and measurement is done on VNA. The proposed multiband antenna can be used for Satellite Communications, Citizens Broadband, IEEE 802.11a system, ISM Equipment, Amateur Radio, Aeronautical Radio navigation and Maritime applications.
