Simple printed monopole slot antenna for penta‐band wireless wide area network operation in the mobile handset

Abstract

A simple printed monopole slot antenna for penta-band wireless wide area network operation (824-960/1710(824-960/ -2170 in the mobile handset is presented. The monopole slot has a length of 50 mm only and is embedded close to the bottom edge of the system ground plane of the handset with a small distance of 11 mm. By adding a smallsize C-shaped strip connected orthogonal to the bottom edge of the system ground plane, good excitation of the monopole slot antenna at its fundamental (0.25 wavelength) and higher-order resonant modes can be obtained. The excited resonant modes form two wide operating bands to cover the GSM850/900 operation (824-960 MHz) and GSM1800/1900/ UMTS operation (1710-2170 MHz). Detailed operating principle and radiation characteristics including the specific absorption rate results of the proposed monopole slot antenna are described. Measured results of the fabricated antenna are also presented.

Eight-Port Orthogonally Dual-Polarized Antenna Array for 5G Smartphone Applications

“…Therefore, a 4-antenna L-shaped monopole slot array is further proposed in this work. The concept of monopole slot antenna design is stemmed from a patent reported in [23], and its merits as reported in [24][25][26] have shown that this design is very suitable for mobile handset designs.…”

A compact slot antenna configuration for ultrawideband (UWB) terminals and mobile phones

“…. Compared with antennas with metal strips or frames, the proposed antenna has lower height and smaller size. Compared with reconfigurable antennas using diodes, no DC bias voltage is required in the proposed antenna.…”

“…There are some literatures published on mobile phone antennas of printed slot type mainly with rectangular shaped slot . However, none of the above comes from UWB configuration.…”

Uniplanar coupled-fed U-shaped monopole antenna for LTE/WWAN operation in a tablet computer

“…The internal antennas for mobile devices such as handsets, laptop computers and table computers operating at GSM850/900/1800/1900/UMTS (824 ~ 896/880 ~ 960/1710 ~ 1800/1850 ~ 1990/1920 ~ 2170 MHz) bands have been presented [1][2][3][4][5][6][7][8][9]. Owing to the LTE (long term evolution) operation, which is recently introduced to provide much higher data rate than the WWAN operation, mainly includes three operating bands in the LTE700 (698 ~ 787 MHz), LTE2300 (2300 ~ 2400 MHz) and LTE2500 (2500 ~ 2690 MHz).…”
