“…This concept has been further applied to develop a simple structure based on the magneto-electric dipole (MED) antenna and proposed by Luk and Wong [10,11]. Many works concerning magneto-electric dipole antennas have been published [12][13][14][15][16][17], including base station antennas [18,19]. In addition, the applied concept of MED with optimal synthesis of the reconfigurable antenna would be a promising candidate for radar applications [20,21].…”

Abstract-This work presents the design of a magneto-electric dipole (MED) antenna for the base station antenna of FM radio broadcasting implementation. The advantages of MED antenna are high gain, stable and symmetrical radiation patterns in both electric and magnetic planes, and low back lobe radiation pattern. The antenna was designed and studied to achieve the optimal dimensions of configuration parameters. The prototype antenna was fabricated and measured to validate its S 11 , radiation patterns, and gain. The impedance bandwidth was 33.49%, and the average gain was 7.78 dBi at the entire operating frequency (88-108 MHz). The measured results are in good agreement with the simulated ones.

“…This antenna can provide wide impedance bandwidth, identical E-plane and H-plane radiation patterns, stable gain and low back radiations [1,2]. Despite the antenna has shown excellent performance with a staircase-shaped structure [3][4][5][6], where additional need of balun may be removed and antenna can provide dual-band with wide impedance bandwidth and high gain, with differential feeding structure [7,8], where the originally single ended operation is converted into differential ended to provide ultra-wide band, theoretically infinite differential port to port isolation and to be directly connected to differential microwave circuits, and with dielectric material [8][9][10], where magneto-electric dipole antenna is printed on dielectric material, it suffers from disadvantages of being bulky and pertaining complex structures. In [11][12][13], circular polarization has been achieved with 3-dB axial ratio bandwidth of 42.9%, 61.5% and 82% respectively, but the magneto-electric dipole antenna structure is non-planar.…”

Abstract-A new design of a circularly polarized planar magneto-electric dipole antenna is proposed and presented. This antenna consists of dual horizontal T-shaped electric dipole and an inverted Ushaped feed line. The antenna possesses 21.1% impedance bandwidth, from 8.9 GHz-11.0 GHz, provides 3-dB axial ratio bandwidth of 9.52% ranging 10.0 GHz-11.0 GHz, exhibits stable omnidirectional radiation pattern with almost equal E-plane and H-plane radiation patterns and provides a peak gain of 6.2 dBi. Due to its good electrical characteristics and radiation parameters, the antenna is suitable for satellite and RADAR communication in X-band.

“…By exciting a loop antenna and a dipole or monopole simultaneously, some composite antenna designs were proposed in [1][2][3]. Recently, a novel kind of composite patch antenna which is also called magneto-electric dipole was investigated in [4,5]. The designs usually consist of a horizontally mounted electric dipole and a vertically placed shorted patch antenna which can be equivalent to a magnetic dipole.…”

Abstract-By combining a horizontal bowtie electric dipole and a vertical rhombic loop antenna which is realized by a pair of folded shorted patches, a very wideband dipole-loop composite patch antenna is designed. Four tuning stubs are attached to the edges of the bowtie dipole to improve the impedance matching. The bowtie dipole and the rhombic loop antenna are excited simultaneously by a simple feed structure which not only forms a folded balun but also makes the antenna itself be direct current grounded. Results show that a wide impedance bandwidth of 121.6% for |S 11 | < −10 dB from 3.5 to 14.35 GHz is obtained. Good radiation patterns, low back radiation, low cross polarization level, and peak antenna gains of 7.7 to 9.8 dBi are achieved over the operating bands.
