A novel extended edge-based compact PIFA antenna for mobile devices

Investigation of a defected ground structure inspired wideband printed monopole mobile antenna using characteristics mode analysis

“…Later, the SAR of the proposed monopole antenna is interpreted using the 3D voxel human phantom head and hand model in Computer Simulation Technology (CST) Studio Suite. The comparison of performance metrics (which includes idea about the antenna configuration, band coverage, SAR analysis and CMA investigation) of proposed antenna with existing ones [1][2][3][4][5][6][7][8][9][10][11][12][13][14] are presented in Table 1, that confirms its significance over others. To explore insights about the antenna, the CMA is vividly studied on its different structural configurations to predict modal resonance characteristics.…”

“…It is combination of a modified crescent‐shaped monopole antenna [monopole mode (M‐mode)], L‐shaped stub [stub mode (S‐mode)], and DGS element (slot mode‐1 and slot mode‐2), capable of generating broadened IBW with multiband operation, that is, 880–960 MHz, 2.3–2.4 GHz, 2.4–2.483 GHz, 3.3 GHz–4.2 MHz, 3.3–3.8 GHz, 5.15–5.85 GHz, and WLAN (IEEE 802.11 b/g/n). It exhibits better performance than the existing antenna designs reported in References 1–14. The averaged SAR 1 g (W/kg) values obtained in these frequency bands is ranging in between 0.0014 and 0.0462 W/kg, which is way under the limits decided by FCC.…”

“…The proposed crescent-shaped printed monopole antenna inspired with DGS is designed for wireless applications, considering its IBW accommodating various bands: 880-960 MHz, 2.3-2.4 GHz, 2.4-2.483 GHz, 3.3-4.2 MHz, 3.3-3.8 GHz, 5.15-5.85 GHz, and WLAN (IEEE 802.11 b/g/n/ac). Antenna performances such as size of the RF frontends, gain, directivity, SAR, and so forth are quite better than the compared literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14] reported in Table 1. The proposed antenna is included in the mobile hand-held terminal and simulated, the validated outcomes show leveraging potentials for the above-stated working bands.…”

“…In general, there is a huge demand of compact multi-resonant mobile antennas in various domains of cellular communications. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] In practical scenario, it is seen that separate antenna modules operating in different mobile bands (sub-6 GHz) has swamping effects of stronger signals coming out from different antennas, often resulted in the frequent RF droppings. Hence, RF device engineers have to come up with a solution to integrate multi-resonant modes into a single design entity.…”

“… Note : Coverage of Bands: GSM 900, LTE, Wi‐Fi, WiMAX, ISM, 5G (5 GHz), n77, n78, LTE Band 46 and WLAN (IEEE 802.11 b/g/n), References 1–14 comes the under the category of partially coverage of the designated bands. …”
