“…A number of technologies have been proposed to realize dual-band or wideband designs for the quarter-wavelength monopole antennas. [1][2][3][4][5][6][7] A technology often adopted is introducing additional resonant elements, and loop antennas are good candidates. A typical design is described by Yildirim et al, 1 where a printed monopole antenna is connected with a shorted loop antenna in parallel.…”

“…Alternatively, injection molding followed by metallic plating processes was employed to form the RWG channels 3 with acceptable return and attenuation loss. Recently, commercial 3D printing technology, 4,5 which is based on layer by layer deposition produces excellent quality, light weight, and inexpensive RWG components. 6,7 However, most of these 3D printed…”

A novel design for monopole antennas with wideband operation and stable radiation patterns is described. The proposed monopole antenna has a three‐dimensional ring‐shaped ground plane, and it can be treated as a monopole‐loop composite antenna. Two pure resonant modes are simultaneously excited in the antenna structure, and their resonant frequencies are respectively at 2.45 and 5.4 GHz. By introducing a pair of shorting posts into the ground plane, the two resonant modes can be coupled together. The resultant impedance bandwidth (VSWR < 2) is about 70% with respect to the center frequency 4.5 GHz. Moreover, a stable bi‐directional radiation pattern with a peak gain of 5 dBi and a cross polarization level of less than −15 dB is obtained within the impedance bandwidth. For the proposed antenna, parametric analyses are performed and an antenna prototype is also constructed. Both measured and simulated results are given.

“…A dual-band printed dipole antenna is designed by combining a rectangular and two L-shaped radiating elements [12]. A dual-meander folded loop antenna [13] is difficult to avoid the defect of huge assembling space and bad mechanical strength. The conical monopole is a well-known antenna with broad bandwidth and good radiation efficiency.…”

Abstract-A compact multiband omnidirectional antenna for the reception of GNSS signals on artillery projectiles is designed in this paper. The proposed antenna consists of a metallic cone comprising a T-shaped monopole. It exhibits a broad bandwidth from 1.22 GHz to 1.28 GHz and from 1.44 GHz to 1.75 GHz, covering GPS L1, Galileo E2-L1-E1, GLONASS G1 and G2, CNSS B1 and B3. Measured results show that an omnidirectional radiation pattern is achieved, and the non-circularity in the azimuthal plane (xy-plane) is less than 2 dB for all the desired bands. Then the measured 6 dB beamwidth is about 110 • in the presence of a finite 20 millimeters (mm) radius ground plane. Such an antenna has the potential to be easily used for small artillery projectiles.

“…In order to cover larger bands researchers have proposed different antennas to cover UWB frequency range from 3.1 GHz to 10. 6 GHz. An UWB antenna senses all the frequency falling in its band but in order to reject busy channel and receive only free channels, multiband UWB antennas are preferred.…”

A printed loop antenna is designed to produce three distinct bands to cover six different frequency bands from UWB groups. Loop is fed using a printed BALUN transformer. The first band is available from 3.09 GHz to 4.44 GHz, the second band is available from 6.11 GHz to 7 GHz and the third band is available from 8.85 GHz to 10.5 GHz. The measured results are in good agreement with the simulated results. Frequency band from 3.0 GHz to 4.44 GHz covers UWB BAND-1 and BAND-2, the frequency band from 6.11 GHz to 7 GHz covers UWB BAND-7 and the last band from 8.85 GHz to 10.5 GHz covers UWB BAND-12, BAND-13, and BAND-14. Antenna rejects IEEE 802.11 Wi-Fi / WLAN band at 5.8 GHz.
