From the last few years we having the difficulty to find out the best dual band because it takes a lot of attention due to the requirement which now days everyone want like size, power and multiple functions. Many bands are available in market in which helix antenna replaced by internal patch antenna which help in communication system.
Best Dual Band Mobile Antenna
Larger number of antennas instead of two or four they fit in very limited space of the mobile phone. We all know that excessiveness of anything can be harmful for us or it can be the reason for our trouble just like that more antennas will bring more new problems. The Global system for mobile communication (GSM-900, GSM-1800), Global positioning system (GPS), wireless LAN, Long term evolution which cover three bands they are increasing the number of service bands with satisfaction in having lightweight, high performance, low frequency.
In lower band in which frequency range is (698-966 MHz) and higher band the range is (3.4-3.8 GHz). In this band Bluetooth works at (2.4-2.85 GHz) frequency which is find in Industrial Scientific and Medical band. In United State and in other country WiMAX used for internet service in which have frequency of (2.3 GHz, 2.5 GHz, 3.5 GHz). So, to satisfy others demands of less distance, high communication system different methods has been used everybody have their own choice like thickness of substrate, different patches with beautiful layers, slots. To increase the performance of antennas meta-material and radiator used.
There is more user which have demand of advance system of communication, high data rate, bandwidth etc. now a days a lot of communication system present like 4G mobile communication , Bluetooth, WLAN , Wi-Fi , GPS, WIMAX etc. if we compare meta material with conventional material structure then meta material have artificial material with dense size and have infrequent properties such as negative permeability, double negative characteristic , negative refractive index etc. these properties are absent in natural materials.
Meta-material antennas are research hotspot due to these properties which enhance the performance of the antennas and nowadays everyone want this. A dual- band mono-pole antenna has an open complementary split-ring resonators which covered the Bluetooth band and the also the size of antenna.Antenna has many shapes like T-shaped feed patch, inverted T-shaped stub and 2 E-shaped stubs which cover the frequency bands from (1.575 to 1.665 GHz) for GPS.
Multiple band antenna introduced for GSM (880 to 960 and 1710 to 1880/1850 to 1990 MHz) and LTE 2300 to 2400 MHz applications. Micro strip path antennas are made for mobile devices. For WIFI and WIMAX applications different frequency is used. main concept of all this is to acknowledge about the design,cost, low frequency bands, better gain, stability of radiation and high frequency of antenna.
A dual band meta-material antenna has a patches with slotted ground place. Combining the two ring resonator with a sequence of splits and metal splits are integrated meta-material structure. Function of metal splits is it connect the upper and lower metal bar of inner ring resonators which is look like Z – shaped structure. Measurement is also compulsory we should have to know the measurements which are .63, 3.21, 3.63 GHz which cover up the bandwidth of 40 MHz if antenna have a changes in shape, structure and the position then it effect many properties of antenna and also effect on performance.
