Hexa-band quad-mode folded monopole/dipole/loop antenna

A novel hexa-band internal folded monopole/dipole/loop antenna has been proposed. The proposed antenna has four resonances in which three of them are 0.5λ, 1λ and 1.5λ modes. The distinctive feature of the antenna is an extra 2λ folded dipole mode, which has not been reported so far, is excited and utilized. All these four modes can be employed to cover the Low LTE700/GSM850/900 Band (LB: 698-960MHz) and the High GSM1850/1900/ UMTS2100 Band (HB: 1710-2170MHz). The proposed loop antenna has been simulated, prototyped and tested. It is shown that the numerically simulated results are in close agreement with the experimental prototype results and proved that the proposed antenna operates as proposed.
