“…The metamaterial which can be used for fabricating the antenna substrate in GHz frequency range is similar to the metamaterial discussed in work [20], Figure 4. This choice is caused by the results of work [21] where the miniaturization of microstrip antenna in the microwave band is achieved by creating the antenna on a planar layered periodic structure. Thereby, it is proposed to consider the substrate metamaterial as a dielectric matrix of parallelepiped form with periodically imbedded Iron or Copper wires of radius r. It is also supposed that Iron wires are partially or fully magnetized.…”

The idea of profile miniaturization and performance improvement of a rectangular patch antenna using a metamaterial substrate with large values in the real part of effective relative permeability is proposed in microwave frequency range. The volume profile of the antenna is minimized by tuning the effective relative permeability and thickness of the substrate material. The specific type of metamaterial which can be used as substrate material for the antenna miniaturization purpose is suggested. The proposed idea is validated through finite-difference time-domain (FDTD) simulations for sample rectangular patch antennas with metamaterial substrates at the frequency about 10 GHz. Improvement of the power directivity is found for the metamaterial substrate with large value in the real part of effective permeability. V C 2016 Wiley Periodicals, Inc.

“…Moreover, the patch antenna for tunable miniaturization factor has been illustrated in [2]. In addition, the literature survey shows that the uses of magneto-dielectric meta-substrate [3], meta-surface [4,5], hybrid optimization [6], proximity effect [7], ceramic materials [8], meta-materials [9,10], and shorting pin [11] are effective ways for antenna miniaturization. Many different techniques for microstrip antenna miniaturization has been illustrated in [12].…”

A higher degree of miniaturization technique is presented based on frequency reduction method for a rectangular patch antenna by introducing a slot on the radiating patch with unchanged antenna configuration. To realize the frequency reduction technique, a rectangular patch is designed to operate at the fundamental frequency. Then a slot on the radiating patch is introduced, and as an effect of slot, fundamental resonant frequency is shifted to the left side of reflection coefficient plot. The percentage of reduction resonant frequency is 65.80% where 2.31 GHz is the fundamental frequency, and 790 MHz is the operating frequency of slot integrated patch geometry. In addition, we introduced another similar slot on the ground plane, and as a result, resonant frequency shifted from 790 MHz to 729 MHz caused by 68.44% reduction in resonant frequency with unchanged antenna dimension. To verify the simulated theory, prototypes are fabricated and complied with measured results.

In this article, miniaturization of dual‐band slot antenna design for GPS, WLAN and amateur radio applications is presented. The proposed dual‐band miniaturized antenna is achieved using slits, rectangular split ring and metallic strips fed by 50 Ω microstrip feed. The first resonant frequency is achieved by loading reference antenna with eight slits that is antenna 1 and the second resonant frequency is achieved by loading with one center slits and rectangular split ring that is antenna 2. Dual‐band antenna is achieved by loading reference slot antenna with nine slits and rectangular split ring which resonates at frequency of 1.52 and 3.03 GHz respectively. As a result, it is achieved 53.79% reduction in first band resonant frequency with 76.07% improvement in −10 dB bandwidth and 7.90% reduction in second band resonant frequency compared to reference slot antenna. Further, this dual‐band antenna is miniaturized by metallic strips which are placed on the bottom of the substrate. This results in 61.39% reduction in first band resonant frequency with 32.07% improvement in −10 dB bandwidth and 26.13% reduction in second band resonant frequency in comparison with reference slot antenna topology.
