“…Furthermore, the proposed antenna has a small protrusion dimension of 0.72λ o , SLL of -10 dBi and FBR of 20 dB. The performance of this antenna is much better than the antennas proposed in [13]- [17].…”

“…Further, the radiation efficiency is limited by 70% at 3.5 GHz due to using high-index of refraction medium. In [17] the authors have deployed an array of folded electric resonators in elevation plane of a standard dipole antenna to realize beam tilting in the elevation plane at 60 GHz. Results show the tilt angle is 2 limited to 30 degrees, and the average gain over 57-64 GHz is 10.9 dBi.…”

A method to significantly increase the gain of a bow‐tie antenna based on metamaterial concept is presented. The μ‐negative feature of the proposed two‐sided planar metamaterial (TSPM) structure is investigated by retrieving its constitutive parameters from the S‐parameters. The proposed structure consists of six slabs that are loaded with a 3 × 3 array of TSPM unit cells, which are embedded in azimuth plane of a modified bow‐tie antenna vertically. The TSPM unit cells provide a medium of low effective permeability. The dimensions of the slabs are 30.6 × 20.6 mm2 at 7 GHz. To show the adaptability of the proposed high‐gain antenna, the structure was designed to cover H‐band applications (6‐8 GHz). Consequently, a small antenna is designed in comparison with initial bow‐tie structures. The corresponding return loss of the antenna is better than 10 dB over 6 to 8 GHz. The proposed metamaterial antenna was manufactured and its characteristics measured to verify the proposed idea. Good agreement between the measured and simulated data is obtained. Maximum gain measured of the antenna is 10.21 dB at 7.5 GHz, constituting a maximum gain enhancement of 7 dB for H‐band in comparison with a bow‐tie antenna without any metamaterial structures.

A highly miniaturized low profile dual band patch antenna loaded with metamaterial unit cell is proposed. The metamaterial unit cell consist of inter digital capacitor (IDC) and a novel modified circular slot ring resonator (MCsRR). The novel MCsRR is a low frequency compact circular slot ring resonator. A microstrip patch antenna circuit analysis depicts that increase in series capacitance can decrease half wavelength resonance frequency, thus reducing electrical size of patch antenna with significant antenna gain. The transmission‐line model of unit cell is analyzed to study pass band characteristic at resonating bands. The proposed antenna have dual band operation with reasonable gain of 2.84 dBi at first center frequency 3.15 GHz with bandwidth of 150 MHz and 3.86 dBi at second center frequency 5.28 GHz with bandwidth of 140 MHz, even though the electrical size of proposed antenna is only 0.199λ × 0.199λ × 0.008λ. The electrical size of proposed patch antenna is miniaturized by 60.10%.
