This work presents a 28 GHz Dual Element Multiple Input Multiple Output (MIMO) Planar Inverted-F Antenna for millimeter wave 5G mobile terminal. The antenna design employs PIFA design concept as it is a common antenna type use for mobile phone as it provides wide bandwidth and good performance. The antenna design begins with a characterization of the single element PIFA design and then extended to Dual Element MIMO PIFA design. The single element PIFA design is enhanced to MIMO design by extending the ground plane and locate the second PIFA at the other end. Isolation between the antenna elements of the MIMO PIFA is analyzed by varying the gap distance between the antenna elements. The result for Envelope Correlation Coefficient, Diversity Gain and Multiplexing Efficiency is also presented. The simulation computed using Computer Simulation Technology (CST) Microwave Studio software.

“…To increase the bandwidth and resonance frequency, the radiator element must be replaced by a plate. The reduced radiation behind the PIFA improves antenna performance in terms of gain and minimizes the wave produced due to power absorption [2][3][4]. We have a maximum gain in terms of polarization states like horizontal and vertical.…”

This paper presents a new design of a multi-band inverted F antenna structure (PIFA) fed by a coaxial line. The design tool is the CST-MW software which uses the finite element method. To create new resonances frequencies it is necessary to insert slits of various forms on the radiation element. The final validated circuit is designed to operate in the Industrial Scientific and Medical (ISM 2.4-2.5GHz), Wireless Local Area Network (WLAN 5.15-5.35 GHZ) and Worldwide Interoperability for Microwave Acces (WiMAX 3.30-3.80). Obviously, it has been found that the radiation patterns of the antenna shown are similar to the bidirectional radiation pattern. For simulated The properties of the antenna, such as return losses and radiation patterns, we used CST-Mw Studio.

“…The driven PIFA element acts as the primary element, governing the lowest resonant frequency, while the upper resonant frequency in the DVB-T band is controlled by the parasitic element. In [5] and [6], substrates are used rather than air. In [5], a dual-band PIFA for LTE and WiMAX applications is proposed.…”

ABSTRACT:A compact Planar Inverted F Antenna (PIFA) as the element for dual band operation in 1.48 GHz GPS and 3.2 GHz WiMAX band is proposed. PIFAs are quarter wavelength elements. Among various possible antennas, PIFAs have the advantages of low profile, compact size and are very suitable for present-day wireless communication application. A folded slit in the top plate is used to get the dual band operation. Comparison between two different orientations for folded slit is performed. A 50% miniaturization and gain improvement is achieved when the folded slit is near to the feed with an open end. The radiation pattern and current distribution on the PIFA are also plotted. KEYWORDS:PIFA, dual band, folded slit, miniaturization I.INTRODUCTIONMonopole antennas and helical antennas (whip antennas) were used as external antennas in early days. They are quarter wavelength elements and can have wide bandwidth. But they cause user interference because of the backward radiation. These were later replaced by internal antennas. Many applications require low profile antennas, especially portable devices such as laptops and mobile phones. Patch antennas and their derivatives are the best candidates for low profile application as internal antennas. Patch antennas are half wavelength elements. Their disadvantage of large dimension and narrow bandwidth led to the introduction of Planar Inverted-F Antenna (PIFA). PIFA have size less than quarter wavelength which is best suited as internal antennas in portable devices. But the main limitation is narrow bandwidth. By adjusting various parameters of PIFA their size can be made smaller and their bandwidth can be enhanced [1].In order to incorporate different standards into a single device, multi band and broadband antennas are required. When the operating frequencies are far apart multi band antennas are preferred over broadband because of the need of multiple filters in case of broadband. In this thesis, a single band PIFA for GPS is designed. Then the top plate is modified to obtain a dual band antenna operating at 1.5 GHz GPS and 3.3 GHz WiMAX. A folded slit structure on the top plate is used for obtaining dual band performance. Two different orientations of slits are compared. II.RELATED WORKSIn [2-6], dual band antennas with parasitic elements to generate higher bands are proposed. The total volume occupied by these antennas is larger than the proposed compact element. In [2], a slim dual-band PIFA in conjunction with Lshaped parasitic is proposed for GPS and WiMAX bands. The size of element is 100 x 24 mm² and the height is 9.8 mm. In [3], a compact dual band PIFA with two meandered metallic strips and one nearly rectangular patch to produce three resonances in the GSM and DCS band is proposed. Height of PIFA is 8.4 mm and the size of radiating element is 24 x 37 mm². In [4], a dual-band PIFA for DVB-T and WLAN applications with overall size of 217 x 12 mm² and height of 8 mm is proposed. The driven PIFA element acts as the primary element, governing the lowest resonant frequ...
