A 1 × 4 planar fractal array antenna is designed and presented for millimeter-wave 5G applications. The array’s top side is made up of a rhombus-inscribed circular ring fractal patch radiator, while the backside is made up of a square notch-loaded partial ground plane. To achieve high gain, a 1 × 4 corporate feeding network is used to excite the array elements. The designed array has an overall size of 28 × 17.75 mm2. From simulations as well as experimental results, it is observed that the designed array offers a wide impedance bandwidth in the frequency range of 22.8–29.2 GHz. Furthermore, a peak gain of 10.7 dBi with a radiation efficiency of > 95% is observed in the operating bandwidth.

“…Angled dipoles are smaller than straight dipoles and have excellent matching performance. In addition, mutual coupling is low when used as an array [13,14]. This paper used an angled dipole because of the abovementioned advantages.…”

“…However, single-printed dipole antennas exhibit low gain, making them inapplicable for use at high frequencies. The radiation pattern of a single-printed dipole antenna is typically asymmetrical, which causes the beam scanning range to present asymmetrically, making it difficult to use for two-dimensional phased array antennas [10][11][12][13]. Metal cavity-backed antenna structures, or Yagi-Uda antenna structures with multiple directors, are used to increase the gain and symmetricity of the radiation patterns [14][15][16][17][18][19][20][21][22].…”

This paper investigated the characteristics of series-fed angled dipole antennas as the number of dipoles increased from one to two, four, and eight. A parallel strip line printed on both sides of the substrate was used to connect angled printed dipoles of the same size in a series with equal spacing. As expected, although the gain increased as the number of dipoles increased, the impedance and gain bandwidths decreased. In addition, as the number of dipoles increased, the half-power beamwidth (HPBW) differences between the xz- and yzplanes decreased and the radiation pattern of the xz-plane became more symmetric. Antennas with one, two, four, and eight-dipole elements in a series were designed, and their peak gains were 5.0 dBi, 7.2 dBi, 9.4 dBi, and 10.4 dBi, respectively. The differences between the xz- and yz-plane HPBWs of the four antennas were 160.4°, 41.7°, 14.2°, and 5.3°, respectively. As the number of dipoles in the antenna increased, the differences between the HPBWs in the xz- and yz-planes decreased.

“…In recent years, several antennas have been published to meet these properties. A quasi-Yagi antenna has been proposed to meet these demands [2,3,4,5,6]. Here a large ground plane is required to act as a reflector which makes the antenna size large.…”
