“…The proposed radial CRLH‐TL can be regarded as an open‐circuited CRLH‐TL. For an open‐ending CRLH‐TL, the shunt resonance appears, and the resonant frequency of the 0 mode is determined by the left‐handed inductance and the right‐handed capacitance 10 :

f_{SH} goodbreak= 1 / 2 π \sqrt{C_{Rr} L_{Lr}}

In this design, the L Lr can be evaluated by regarding the shorted pins as wire inductor, as explained in Ghosh and Das 22 . The C Rr can be evaluated by regarding the combination of the radial radiator and the metal ground as a plate capacitor.…”

A compact multiple‐input multiple‐output (MIMO) antenna is proposed with dual‐mode pattern diversity. A two‐port antenna with a single radiator is designed based on the composite right/left‐handed transmission‐line (CRLH‐TL) theory. An omnidirectional radiation pattern is excited by the port 1, while a directional radiation pattern is excited by the port 2. When the omnidirectional radiation pattern is excited, the antenna can be regarded as a radial CRLH‐TL‐based resonator. When the directional radiation pattern is obtained, the antenna is modeled as a circular patch antenna. The two different radiation patterns are integrated in one antenna with low complexity and low cost. The electrical size of the proposed antenna is 0.6 × 0.6λ2 (at 3 GHz). A low profile of only 0.07λ is obtained. The antenna works at the 3 GHz band. The measured −10 dB bands for port 1 and port 2 are 2.71–3.06 GHz and 2.87–2.96 GHz, respectively. A low mutual coupling below −30 dB between the two radiators is achieved, which decrease the channel correlation significantly.

In this article, an antenna with the combination of the microstrip slot and Yagi antenna is presented for wideband WLAN (wireless local area network) using CRLH (composite right/left‐handed) as a metamaterial (Left‐hand) element. The T‐shape feed line is investigated as a radiator section and modified for enhancing the bandwidth. The periodic elements are utilized as a novel type of the director to improve the bandwidth to more than 35% and increase the gain of the antenna to more than 80% where the three CRLH elements array are employed as the director of the Yagi antenna. The proposed antenna covers the 2.2 to 8 GHz (113% bandwidth) with a return loss of less than −6 dB (VSWR less than 3), which makes it suitable for wireless applications for covering different bands including WLAN, LTE (Long Term Evolution), and WiMAX with 47% miniaturization. The final antenna is simulated with CST microwave studio by the time‐domain method of FIT (Finite integration technique). The total size of the antenna is 60 mm × 40 mm × 1.6 mm, which is printed on an FR‐4 substrate, and the experimental results confirm the simulations.
