Parametric study of dual-band operation in a microstrip-fed uniplanar monopole antenna

Design and Optimization of a Logo-Type Antenna for Multiband Applications

“…This study optimizes seven parameters, and adopts the OA (18,7,3,2) [18] for optimization. The OA in Table 2 offers 18 experiments in one iteration.…”

“…Figure 1 illustrates the geometry of the proposed antenna. In the proposed design, a 50 ohms microstrip feeds the antenna [3]. Since the radiating elements of the antenna consist of many strips, exciting different modes makes the antenna suitable for multiband purposes [4].…”

Compact broadband folded monopole antennas with shorting pins

“…Broadband planar monopole antennas with compact dimensions have potential applications for multiband mobile phones [1][2][3]. By increasing the width of patch, its bandwidth was increased, as compared to that in [3].…”

“…By increasing the width of patch, its bandwidth was increased, as compared to that in [3]. It is difficult to accomplish a folded patch using a planer substrate.…”

“…In this paper, we propose a design of broadband folded monopole antennas with shorting pins. The proposed folded monopole has compact dimensions of 6 ϫ 40 ϫ 0.8 mm 3 , and shows a very wide bandwidth of 965 MHz, from 1.66 to 2.62 GHz, and the bandwidth covers the DCS (digital communication system, 1710 -1880 MHz), PCS (personal communication system, 1850 -1990 MHz), 3G (3 rd -generation wireless, 1920 -2170 MHz), and WLAN (wireless local area network, 2400 -2484 MHz) bands. Broadband and omnidirectional radiation Figure 1(b) shows the proposed broadband folded monopole antennas with shorting pins.…”
