In this paper, a wearable ultra‐wideband (UWB) monopole antenna with a compact structure and low profile is presented for wireless body area networks, wireless local area networks, and UWB applications. The antenna is composed of three triangular radiators on the basis of the mono‐cone antenna. By the methods of reactive and slot loading, the dimension of the antenna can be greatly reduced. The overall height of the antenna is 0.06 λ0 at its lowest operating frequency. The radiated structure of the proposed antenna with the dimension of 31 × 31 × 9 mm3, which operates in 2.3 to 12.6 GHz, is fabricated and the measurement results are in good agreement with the simulated ones. Moreover, the influence of the human tissue on the antenna was evaluated, and stable performance can be obtained on the human tissue under different bending conditions. The specific absorption rate values are lower than the limitation set by the European Telecommunications Standards Institute, which indicates that the antenna is suitable for wearable applications.

“…To further reduce the antenna profile and overall volume of UWB antennas, some designs [20]- [22] with extremely compact size have been reported for some specific applications. However, these designs use either resistive loading [20], [21] or lossy ferrites [22] loaded inside the antennas to achieve improved impedance matching at the cost of low realized gains.…”

This paper first proposes a 3D printed, compact, low-profile, ultra-wideband (UWB) antenna with vertically polarized omnidirectional radiation characteristics. The antenna is composed of one triangular feeding structure, one triangular shorted structure, a common capacitive top hat, and two parasitic metallic pins. Compared with traditional UWB antennas with symmetrical configuration, the proposed UWB antenna is a three-dimensional version of inverted ''F'' with asymmetrical structure. The proposed antenna can realize compact aperture and low profile (0.19λ L × 0.19λ L × 0.06λ L , where λ L is the free-space wavelength of the lowest operating frequency). Two parasitic pins are utilized to enhance the omnidirectionality of the antenna in the azimuth plane. The impedance bandwidth is greater than 10:1 (2.96-30 GHz) for VSWR < 3, and the bandwidth with horizontal radiation pattern ripple better than ±5 dB is more than 4.9:1 (2.96-14.5 GHz). Second, this UWB design is modified to realize dual bands with a deep band-notch by adding a split gap inside the antenna. The proposed band-notched antenna is designed with the bandwidth of 2.4-2.5 and 5-10 GHz for VSWR < 2 with good horizontal radiation pattern omnidirectionality, which can be used for 2.4/5 GHz WLAN applications. The prototypes of the proposed UWB and band-notched antennas are fabricated by metallic 3D printing, and the simulated and measured results meet well.

“…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].…”

“…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.
