“…Likewise, several other authors were successful in getting an impedance bandwidth above 12% by experimenting with the resonant modes [9][10][11][12][13]. It is evident from the results presented in [14,15] that with a proper feeding arrangement, the operating bandwidth can be extended above 28%. Nevertheless, this scheme is inappropriate for execution in an electrically thin substrate.…”

The extending applications for mobile computing have experienced immense progress over the previous decade. However, this has ultimately influenced the shortage of bandwidth. Therefore, to fulfill the consumers' demand, inexpensive antennas need to be uniquely designed for the next/fifth generation (5G) frequency spectrum. Consequently, this paper presents a novel antenna composed of inductors (L) or capacitors (C) on an air-substrate. Zinc (Zn) and copper (Cu) materials are utilized to fabricate the lumped LC resonator prototype. The effects of antenna's and substrate's thickness on resonant frequency or bandwidth have been studied. The finalized configuration engaged 1113 sq. mm area and operated at 28 GHz with approximately 3 GHz bandwidth. At resonant frequency, the system demonstrates peak gain and efficiency values of 10.6 dBi and 91%, respectively. The core objective of this paper is to report an antenna featuring simple and economical design along with premium results for 5G mobile terminals.

“…Magneto-electric antennas in free space applications are relatively notable for substantial and stable gain [8]. The observed fluctuation and attenuation in gain towards the high frequencies hypothetically are due to absorption effects of the biological material surrounding the IMEA.…”

“…The complementary antenna is made up of a planar dipole and a shorted patch that is vertically-oriented. The two constituents of the antenna represent an electric and a magnetic dipole, respectively, and when these two are excited simultaneously and appropriately in amplitude and phase, a unidirectional pattern is realized with identical E and H planes [7][8][9].…”

An implantable magneto-electric antenna (IMEA) aiming for operation at ultra-wideband (UWB: 3.1-10.6 GHz) frequency spectrum is presented for biotelemetry usages for the first time. The IMEA is composed of a horizontal planar bowtie radiator, from which its middle part excites the antenna, and a vertically inclined rectangular radiator. The two radiators are complementary and correspond to electric and magnetic dipoles, respectively. The radiators are built over a square dielectric material (ε r = 6, σ = 0.0005) with a cavity for embedding suitable accompanying circuitry system. The IMEA with its biocompatible insulator (PEEK: ε r = 3.2, tan δ = 0.01) measures 1456 mm 3 in volume. HFSS software was used to carry out numerical optimization of the IMEA with a simple multilayered model of body tissue (Skin, Fat and Muscle) as the host environment. The simulated result of the proposed IMEA shows over 90% impedance bandwidth (S 11 < −10 dB) and records a remarkable high gain of 2 dBi within 70% bandwidth. The radiation efficiency is around 50%, and a unidirectional radiation pattern with little back lobe is observed.

“…Thus, a single antenna element with wide beamwidth must be required to overcome the issues of the conventional phased array antenna structures. Although there have been previous researches for antennas having wide beamwidth characteristics such as Huygens source antennas [1][2][3], magneto-electric dipole antennas [4][5][6] and planar magnetic dipole antennas [7][8][9], they suffer from either complicated geometry, very narrow bandwidth, high profile, onedimensional expansion of beamwidth or need for a large ground plane. To overcome these drawbacks, a new planar antenna concept based on multipole radiation element has been recently proposed [10].…”

Electrically conformal antenna arrays (ECAA) for 2-dimensional (2-D) beamforming configured by wide beamwidth multipole radiation elements are proposed. Unlike the conventional conformal antenna array with physically curved shape, the proposed arrays are planar structures with wideangle beam steering. The wide range of beam steering with a low gain variation allows the planar array structure to achieve the electrically conformal phased array patterns. In order to verify the ECAA concept, two different types of ECAA in a 1x8 configuration using planar multipole antenna elements were fabricated at 5.8 GHz and compared to the conventional patch array. Each multipole element had halfpower-beamwidth (HPBW) wider than 110° at both E-and H-planes with the maximum HPBW of 175°. The first type of ECAA showed a measured peak gain of 10.8 dBi with a measured half power steering angle of 155° while maintaining a side lobe level (SLL) less than-10 dB. Further, the second ECAA showed a measured peak gain of 12.8 dBi with a measured half power steering angle of 144° while keeping the SLL less than-10 dB. These scan angles of the first and second types were extended about 66.7% and 54.8%, respectively from the conventional patch array with the same size. Lastly, two types of 8x8 array modules for 2-D beam steering were verified at 5.8 GHz and the first type showed a maximum peak gain of 21.0 dBi. Further, the 2-D half power steering angles in E-and H-planes of the second type were about 145° and 137°, respectively.
