Multi Band Antenna Design for Mobile Devices

2019 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2019
A laser direct structuring (LDS) antenna for multiband operation covering the GSM-850/900, GPS, DCS-1800, PCS-1900, UMTS-2100, WLAN-2400, LTE-2500 bands in the 5G communication devices is presented. The proposed antenna achieves this by exciting the antenna's wide radiating plate.

Design of quarter-wave multi-section multi-band devices

ICECom 2013, 2013
We present a method to design quarter-wave multi-section lossless devices which, in principle, works whatever the requested reflection/transmission spectrum may be. Some examples are reported confirming that our method allows to obtain devices exhibiting a reflection spectrum which can be considered a valid approximation to the requested one for both ...

Multi-band lte antenna for wearable devices

2017 Sixth Asia-Pacific Conference on Antennas and Propagation (APCAP), 2017
Wearable devices have smaller PCB size compared with smartphones or tablet devices, which will bring difficulties in designing LTE antenna with low band coverage. This paper presents two multi-bands LTE antennas for wearable devices with LTE low band coverage.

A Compact Multi-band PIFA Antenna for Mobile Devices

2012 International Conference on Computer Science and Electronics Engineering, 2012
A simple compact multi-band planar inverted-F antenna(PIFA) for mobile devices is presented. The particular shape of the proposed PIFA patch is a compact rectangle with several slits. These slits separate the patch into two resonant paths, generating two bands of about 900 and 1800MHz. The obtained bandwidth covers CDMA, GSM, DCS1800, and PCS1900 bands.
