-Microstrip patch antenna is being studied by the researchers since last three to four decades as one of the standa rd planar antenna. Still, it has much room for further improvements. This paper represents methods to achieve the multi-band microstrip patch antenna using single or multi-element via stack or array & comparison of them. Methods will describes to obtain desired requirements such as wideband, high gain and miniaturization. This are the areas in which further research work can be done to enhance the experienc e of the wireless communication. For better understanding some recently developed antenna designs are described & compared here.

“…For the unidirectional antenna, multiple bands could also be achieved by stacking multiple patches with different sizes, however which leads to high thickness and complexity [6]. Another proposed solution to achieve multiband operation with unidirectional radiation is inserting U-shaped slots in the radiator [7]- [9]. However, such kind of antennas have a poor polarization purity over the different bands, and thus it is not appropriate for using as a transmitter.…”

Abstract-A novel multiband patch antenna with unidirectional radiation is proposed by integrating resonators in the design. The multiple frequency bands are achieved based on a coupled resonators network. The topology and design methodology are detailed. The patch not only works as the lastorder resonator of the network but also the radiating element. Using this approach, multiple bands can be achieved without changing the shape of the radiation element. In addition, the operation bands can be adjusted by adjusting the coupling between the resonators. In this work, the four bands are designed at 4.6, 5.05, 5.8 and 6.3 GHz as a proof-of-concept. The prototype is fabricated and tested and measured results agree very well with the simulations, showing an excellent performance in terms of impedance matching, radiation patterns, gains and cross polarization discrimination (XPD).Index Terms-Multiband, patch antenna, resonator-based, unidirectional.

“…There are many ways to incorporate more than one band in a single antenna. But incorporating U slot cutting inside the patch is one of the effective methods to make an antenna dual or multiband [7][8][9][10][11][12]. U slot is a combination of two vertical slots and one horizontal slot connected to each other to make the U-slot shape.…”

Wireless networks are becoming universal day by day which gives freedom of movement and flexibility in wireless communication. This technology is developing and it has many possibilities in future. Different wireless applications or facilities are available in different frequencies. So, an antenna with multiple frequency bands, which is essential part of this system, has greater acceptance in this regard. In this paper, a dual band rectangular microstrip patch antenna (RMPA) has been proposed for WLAN and WiMAX application. Cutting U-slot inside the patch is used to obtain the dual band characteristics. The dimension of patch of the antenna is 42×26×3.2 mm 3 where FR4 material has been used as substrate. The antenna operates in the 2.40 GHz WLAN range and 3.45 GHz WiMAX (3.2 -3.8 GHz) range with return loss -23.3 dB and -20.2 dB respectively. It reaches 5.4 dBi gain and 6.8 dBi directivity at 2.4 GHz and 3.33 dBi gain and 8.1 dBi directivity at 3.45 GHz resonant frequency. WLAN is widely used for internet connectivity worldwide and the most important application offered by WiMAX Technology is business, consumer connectivity, and backhaul. Hence the proposed antenna is a promising one for practical WLAN and WiMAX devices.
