Because of the antenna's compact size, the antenna's compact size can be operated at up to 3. 5GHz thanks to the use of neutralization lines as conducting strip. The ring antenna mount mounts provide a more consistent dual-band response due to the incorporation of a quarter wave transformer with a semicircular ring design. Due to the combination of tuned semicircular ring and circular ring as well as the conducting strip in the building, the upper resonance of 3. 5GHz is achieved.

For RF energy conservation over 2. 45 GHz WLAN communication applications, we recommend a modified version of a microstrip patch array antenna. Initially, a one-patch and a two-patch array antennas were produced and used as the basis for the construction of a four-patch array antenna in the GSM 1800 frequency range. A radiofrequency WLAN connection, the planned array antenna, impedance network matching, a voltage rectifier, and a storage circuit that achieves higher efficiency are among the WLAN application model's energy consumptions.

In this paper, a new approach to achieve tri-band success for both reduced and conventional size circular microstrip patch antennas packed with low loss metamaterial unit cells is presented. This work, other than miniaturization, mainly focuses on multiband operation with results enhancement of the circular patch antenna Numerical simulation of the original antenna indicates that each band's operating frequencies can tune separately.

In this paper, a metamaterial-inspired miniaturized quadband antenna is developed and discussed with a transmission line device to investigate the theory of miniaturization and multiband. A traditional printed monopole antenna is envisioned as a primary antenna and then enclosed by a grid of 4 2 interdigital LHMs. The experimental findings confirmed the theoretical conclusion, finding that the new antenna is a good candidate for wireless communications applications.

The two MM configurations' different refractive indices caused phase change for the antenna's electromagnetic wave, which deflected the main beam. As an MM unit that will operate within the MMW band, a contiguous squares resonator is suggested. The simulation results of the proposed antenna loaded by MM unit cells show that the radiation beam is deflected by angles of +30° and 27° in the E-plane, depending on the configuration of the two MM configurations on the antenna substrate. For both deflection angles at 28 GHz, the MM antenna's reflection coefficients are held below 10 dB.
