Multiband slot‐loaded dipole antenna for WLAN and LTE‐A applications

Abstract

A multiband printed dipole antenna for wireless local area network (WLAN) and long‐term evolution‐advanced (LTE‐A) applications is investigated here. Its multiband characteristic is enabled by the Y‐slot present in the upper arm of the dipole, while the antenna's dimensions are at the lowest operating frequency. It features bandwidth of 14.6% centred at 2.4 GHz, and ∼30.5% centred at 5.5 GHz for WLAN operation. An additional bandwidth of 6.9% centred at 3.5 GHz supporting LTE‐A applications is also featured. Besides being compact, the proposed antenna radiates omnidirectionally with a gain of up to 4.09 dBi. Simulations and measurements are in good agreement.
