Square Rod Antenna Covered by Mantle Cloak with Rejection Band at Lower Frequency Side of Operating Frequency

Abstract

Mutual coupling reduction is required to miniaturize wireless devices in many applications. The mantle cloak technique has been studied to reduce mutual coupling. This paper proposes a square rod mantle cloak antenna with a low-frequency rejection band. The rejection band is 720 MHz and the operation band is 750 MHz. The proposed antenna structure contains a copper rod-covered dielectric substrate with strip conductors at the center of each face. The proposed antenna was validated by comparing the simulation and measurement results.
