Multi-band Micro-strip Patch Antenna for C/X/Ku/K-Band Applications

In this paper, a multi-band E-shaped antenna is presented for C, X, Ku, and K-band applications. Proposed antenna consists of E-shaped radiating patch and defected ground plane. Introduction of partial ground plane in the design causes decrement in surface waves and increment in antenna gain. The proposed multi-band micro-strip patch antenna has been simulated and optimized using ANSYS HFSS version 15. The proposed antenna uses the FR4 substrate with thickness 1.6 mm, dielectric constant (Ɛ) 4.4, and loss of tangent (tan δ) 0.02. Micro-strip feed line (λ0/4 mm) with 50 Ω characteristics impedance is used for excitation of proposed antenna.
