“…This method exhibits higher capacitance compared to the conventional interdigital method [47][48][49][50]. The capacitive value of the interdigital method is typically produced by the finger between the transmission line and the semi-ground [26], [27] but the double interdigital technique adds an extra finger to the semi-ground, leading to a significant increase in the capacitive value between the transmission line and the semi ground on the unit cell structure. In evaluating the structure of the proposed unit cell depicted in Fig.…”

“…In addition to the ICPW [26], [27], [40], [41] infrastructure that enhances the capacitance between the transmission line and the semi-ground to control the resonant frequency, it was discovered that the capacitive value of the double interdigital range, that is CD value, can substantially increase the capacitive value on the unit cell structure for controlling resonance in the desired frequency range. These values are dependent on the number of fingers, the finger's width, and its length.…”

“…Various metamaterial design techniques, such as frequency-selective surface (FSS) [12][13][14][15][16], involve creating materials with specified transmittance properties or the ability to reflect a specific frequency range. In addition, there is a metamaterial design technique called EBG [17][18][19][20][21][22][23][24][25][26][27] that is utilized as an antenna reflector. EBG structures are defined as periodic objects capable of preventing the propagation of all electromagnetic waves within a specified frequency band for all incident angles and polarization states [28][29][30][31].…”

Wireless communication technology evolves to meet current needs, focusing on antenna size reduction for smaller, multi-frequency devices. This research introduces a novel approach to miniaturizing a multiband Electromagnetic Band Gap (EBG) reflector using a Double Interdigitated Coplanar Waveguide (DICPW) structure. The mushroom-patterned EBG unit cell, employing a double interdigital technique based on a Coplanar Waveguide (CPW), achieves a significantly slower wave on the transmission line. The unit cell size can be reduced from λ/2 to λ/8, allowing control over the second to fourth resonance frequencies. Engineered for a fundamental frequency of 1.8 GHz (LTE), the proposed EBG unit cell supports frequency ranges of 2.45 GHz (WLAN), 4.3 GHz (Altimeter), and 5.2 GHz (WLAN). Integrating this EBG reflector with a dipole antenna at the same frequency results in directional radiation patterns and gains of 8.29 dBi, 8.76 dBi, 8.55 dBi, and 8.22 dBi at resonance frequencies. The innovative reflector, with improved gain and compact dimensions, is relevant to cube satellite and wireless communication systems with versatile multiband frequency requirements.

A compact antipodal Vivaldi antenna (AVA) with metamaterial half-lens (MHL) for beam control is proposed. The proposed AVA has three different beam forms in the operating frequency band, including end beam from 3 GHz to 9 GHz, beam splitting at 12.2 GHz, and 30 ∘ beam deflection at 13 GHz. Furthermore, it can perform 18 ∘ beam scanning by adjusting operating frequency from 12.7 GHz to 13.5 GHz. The simulation indicates that the proposed AVA has a −10 dB impedance bandwidth of 143.6% (2.3–14.0 GHz) and a −3 dB gain bandwidth of 100% (4.5–13.5 GHz), which is consistent with the experimental results. Besides, the gain of the proposed AVA has an improvement of about 2 dB in the working band. As a new method to control the beam, the loading of MHL realizes the design of a small size and multi-function antenna, which can be widely used in wireless communication systems.

This paper presents the design and simulation of patch antenna loaded with metamaterial called Complementary Split Ring Resonator (CSRR) with increased gain and bandwidth suitable for wireless applications such as satellite, TV and radar applications. FR4 substrate with dielectric constant (εr ) of 4.4 is used. The radiating patch consists of CSRR structure fed by microstrip line to achieve triple(C, X, Ku ) band characteristics. The proposed antenna is designed and simulated using Ansys High Frequency Structural Simulator (HFSS). The proposed antenna with 4 rings having a resonant frequency of 7.662, 9.8510, 10.9455, 11.8410, 12.7365 and 13.7315GHz and the bandwidth of 230, 1090, 640, 580, 620 and 2000MHz respectively. The proposed antenna with 6 rings also having a resonant frequency of 7.7615, 9.9525, 11.0450, 11.9405 and13.7315GHz and bandwidth of 160, 1130, 490, 1360 and 1480MHz are achieved. The proposed antenna is analyzed in terms of return loss, VSWR, gain and bandwidth. The electric field and surface current distribution were observed for the proposed antenna having 6 rings.
