In the recent era of wireless communication, Microstrip antenna (MSA) is hot research topic attracting attentions of many researchers. But MSAs have few foremost drawbacks viz narrow impedance Axial Ratio Bandwidth (A.R.BW), low gain and power handling capability. To overcome these drawbacks, novel hybridization method is proposed. A hybridization method includes array method, parasitic patch on superstrate cover and multi stacking instead of the conventional superstrate cover.To achieve the high efficiency, air is used as dielectric medium between feed patch and ground plane as well as between superstrate and feed patch. Due to low cost, availability and ease of fabrication FR4 material is used as superstrate. Proposed system is implemented using FR4 and the results of simulation clearly indicate parametric variations for the various hybrid methods.

“…MTM antennas can overcome this restriction by using leaky wave antenna [19], EBG antenna [20] or array antenna [21][22][23] techniques similar to microstrip antennas [24]. In [21], broad bandwidth and high gain are achieved by using 3 × 2 and 3 × 3 U-slot array antennas. Another U-slot based single layered wideband high gain 2 × 2 array antenna is presented in [22].…”

“…Proximity coupling with air gap is used for bandwidth enhancement while array formation is done to achieve higher gain. Besides wideband and high gain properties, microstrip array antennas face a problem of large footprint area [21,22]. Traditionally, microstrip array antenna uses T-junction for the feeding network [22,23,25,26].…”

Abstract-A compact coplanar waveguide (CPW) fed close ring resonator (CRR) loaded four-element metamaterial (MTM) array antenna for wireless application is designed and discussed in this article. The array is designed with corporate feeding network, arranged in a manner to offer 3 dB power at its each element. The proposed 1 × 4 MTM array antenna offers a fractional bandwidth of 10.18% with respect to the resonance frequency of f r = 2.26 GHz. At the resonance frequency of 2.26 GHz, the proposed 1 × 4 MTM array antenna offers a gain of 5.10 dBi in the direction of broadside radiation. Each element of the proposed array antenna consists of CRR, which removes the requirement of via and allows the design of a uniplanar MTM array. The overall electrical size of the single element antenna shows compactness of 0.255λ 0 ×0.155λ 0 ×0.012λ 0 , where λ 0 is the free space wavelength at its resonance frequency of f r = 2.3 GHz. The proposed MTM array antenna is designed and simulated on ANSYS HFSS 14.0, and simulated results are verified with the fabricated proto-type.

Abstract-A novel high-gain and high-power cavity slot antenna is presented in this paper. The antenna consists of a slotted cavity cover, a driven antenna and a polarization twist reflector. The driven antenna is a balanced-fed dipole. And a 2 × 4 slots array is etched on the top surface of the cavity cover. To excite the cavity slots with uniform amplitude and phase, the polarization twist reflector is used here. Compared with the antenna without the twister, the gain is improved by almost 4.0 dB across the operating band. In addition, the field distributions of the proposed antenna are analyzed through simulation, which proves a high power-handling capacity of 3.94 MW. To verify the design, a prototype operating at 5.8 GHz band has been fabricated and measured. The measured maximum gain and radiation efficiency are 13.6 dBi and 95%, respectively.
