A Novel Slotted Cavity-Backed Patch Antenna for Dual-Band UHF Applications
A novel slotted cavity-backed patch antenna with defected ground structure (DGS) is proposed in this paper. This slotted cavity-backed antenna is composed of a square patch with a metal square-loop as radiator, a cross-shaped slotted square patch as defected ground structure (DGS) and a metal backed-cavity. Both of the square patch and metal square-loop have four square slots. Simulated results shows that the impedance bandwidth with a return loss better than l0dB is 6MHz at 420MHz and the impedance bandwidth is MHz at 480MHz. The antenna exhibits stable radiation pattern over the operation frequency band. The profile and size of the proposed RHCP antenna are 1.0mm (0.00lλ0) and $\mathbf{77mm\times 77 mm(0.12\lambda_0}\times 0.12\lambda_0)$, both of which are extremely small.
