“…A number of studies on indoor base station antennas have been published in journals and conference papers. According to [5], in 1997 the main design target for an indoor base station antenna and the effect of the ground plane were introduced. A design for a cylindrical monopole antenna was proposed to reduce the physical antenna size [6].…”

In recent years, MIMO (Multi-Input Multi-Output) transmission technique has attracted increasing attention, as it can satisfy the need for exponential increase in data traffic for mobile communications, especially when used for indoor areas. In this paper, an antenna design is proposed that can operate in the 2.6 GHz and 3.5 GHz bands and produce an orthogonal bidirectional radiation pattern. Some characteristics of the proposed antenna, such as reflection coefficient (S 11), transmission coefficient (S 21) and far-field radiation pattern are simulated and evaluated by means of FDTD (finitedifference time-domain) methods. The results show that S 11 and S 21 are below −10 dB and −15 dB, and moreover, the MIMO performance can probably be improved because the difference between the two directional gain levels is achieved by approximately 15 dB when four slits are etched into the ground plane.

“…There has been growing interest on multiband loop antennas for mobile communication systems due to their unique multimode features [1][2][3][4][5][6][7][8][9][10][11]. Up to three resonant modes can be generated with a single loop antenna, which offers unique advantages over a conventional Planar Inverted-F Antenna (PIFA) and monopole antenna.…”

“…Up to three resonant modes can be generated with a single loop antenna, which offers unique advantages over a conventional Planar Inverted-F Antenna (PIFA) and monopole antenna. The loop antenna can be considered as a folded monopole antenna operating an unbalanced 2 × ¼ λ (0.5λ) mode [1] and 2 × ¾ λ (1.5λ) mode [2,5]. Also the loop antenna can be perceived as a folded dipole antenna operating a balanced 2 × ½ λ (1λ) mode [3].…”

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.
