“…In the case of placing multiple DF antennas on different planes, the boresight gain of the antenna located at the back becomes low due to the configuration and material properties of the antenna located in the front. There are many studies on DF systems using multiple antennas; however, the antennas were generally placed on the same planes and mainly aimed at detecting targets in the perpendicular directions related to the body axis [1,[4][5][6]. Further, most studies have not considered situations in which conductor material or other devices are located in front of the antennas.…”

In this letter, a direction-finding (DF) antenna inserted into the surface of a cylindrical conductor body, with the conductor material in front of the antenna, is presented. To minimize a gain reduction in the axis direction of the cylindrical conductor, an aperture of an openended waveguide antenna is modified, and the conductor body is deformed. The antenna is operated at the X-band, and its direction finding performance using an amplitude comparison method is analyzed. To verify the validation of the performance of the antenna, the analyzed results are compared to the measurement results.

“…The planar monopole antenna offers these physical features and characteristics [1][2][3][4][5][6][7][8]. Moreover, various antennas with wideband and small size have been reported for UHF band applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Some are unable to operate in the whole UHF band, owing to their small size [2][3][4][5][6][7][8].…”

“…In addition, although the antenna indicates for wideband characteristics, they have three-dimensional (3D) structure and large ground plane [9][10][11][12][13][14]. The other antenna varieties are able to cover the UHF band, but they are relatively large in size [15][16][17][18][19].…”

A novel wideband planar monopole antenna is proposed for wireless communication services and digital TV broadcasting signal reception in the ultra‐high‐frequency (UHF) band. The proposed antenna is a variation of the conventional planar triangular monopole. To obtain wideband characteristics and high gain, a notch is cut at the top side, and several steps are added to the oblique sides of a triangular patch. In addition, slopes are created at the front‐ and back‐side ground planes, in order to further increase the bandwidth. Impedance matching has been optimised by adjusting the gap between the patch and the ground plane. The measured results show that the bandwidth is 2610 MHz in the range of 450–3060 MHz (148.72% bandwidth), which covers the entire UHF band. In the operating frequency range, the peak and the average peak gains in the E‐plane were 2.73–6.09 and 4.62 dBi, respectively.

A novel relatively small wideband antenna is introduced for the mobile application of direction finding (DF) systems covering the frequency range from 150 MHz to 3 GHz. The proposed directional wideband antenna is a rounded‐edge directed bow‐tie antenna which is electrically small when considering at lower operating frequencies. A good agreement is obtained between the simulation and measurement results of the designed antenna. The performance of the antenna for DF applications is verified both in anechoic chamber measurements and in open field measurements. In addition, in open field DF measurements the proposed antenna is compared with a commercial antenna. During the tests, one of the angle of arrival estimation technique based on phase differences of the signal at the antenna elements, interferometer method, and combination of the phase differences and amplitude values of the captured signal were used. As well as, k‐means clustering used to reduce undesired error due to environmental effects.
