Abstract-In this study, a low-profile slot antenna was designed with the purpose of having the ability to be integrated into the structure of a layered non-metallic polymer battery. Using a set of previous published parameters for the slot antenna, the structure was modified in the CST Microwave Studio package in order to suit the needs of a battery substrate. A second slotted ground plane was attached beneath the antenna. The composite substrate and ground planes replicates the layered structure of a plastic planar battery, with the intention of reducing the size of the slots on the bottom plane which also acts as a battery terminal. The effect of the slot size and tan value of the substrate on the radiation patterns was also investigated.

The aim of this article is to design a new microstrip-fed patch antenna for cell phone applications. The antenna design is composed of slots and FR-4 dielectric substrate fed by a partial ground plane and a microstrip line. The user's effects on antenna performances are also analyzed using standard SAM phantom. The specific absorption rate (SAR) values of proposed antenna are evaluated for different frequency bands considering cheek position of talk mode. The proposed antenna has an impedance bandwidth (-10 dB reflection coefficients) 100 MHz (0.87-0.97 GHz, lower band), 50 MHz (1.47-1.52 GHz, middle band), and 150 MHz (1.78-1.93 GHz, upper band), which can cover GSM 900 MHz, GPS 1,500 MHz, DCS 1,800 MHz, PCS 1,900 MHz, and GSM 1,900 MHz bands. Moreover, the proposed antenna produces lower SAR values in the human head than that of a dipole and helical antenna.

“…But the metallic rim affects the radiation performance of the antenna inside the mobile phone [1]. The solutions to these undesirable coupling were discussed in [1] and [2]. Later in [3], the unbroken metal rim itself was proposed as an antenna for hepta-band applications which would save all the undesired coupling, saving enormous space inside and providing a mechanical stability.…”

This paper presents a new two-element multiple input multiple output (MIMO) antenna for LTE application using an unbroken metallic rim as the primary antenna and a non-resonant capacitive coupling element (CCE) as a diversity antenna. The primary antenna covers 698-960 MHz and 1710-2690 MHz and the diversity antenna cover 1710-2690 MHz Average efficiencies above 70% and 50% have been achieved by the metallic rim antenna and non-resonant CCE respectively. A trapezoidal shaped feed is used to improve the high band performance. The unbroken metallic rim provides extra mechanical stability to mobile phones and saves the antenna space. Good isolation between the antenna elements has also been achieved. Both antennas are optimized by efficient matching circuits and conform to the requirements of ultra slim modern mobile phones. Index Terms-4G, MIMO, CCE, non-resonant antenna, characteristic mode,.I.
