“…However, their use in certain systems is limited as the single microstrip patch antenna has relatively low gain and narrow bandwidth with low efficiency. A lot of studies have been published on performance improvement of patch antennas, some of which are: (i) use of large number of patch antennas in array configuration [5, 6]; (ii) increasing the substrate thickness [7, 8]; (iii) optimizing the impedance matching of microstrip patch antenna by use of shorting pins, plates, posts, etc. [9, 10]; (iv) using high-permittivity substrates [11, 12]; (v) modifying the basic patch shape [13]; (vi) using multiple substrates [14]; (vii) loading conventional patch antenna by artificial materials [15–27], etc.…”

To utilize the manipulation of wave properties by metamaterials, in this paper, a microstrip-fed patch antenna array, loaded with metamaterial superstrate, has been proposed. Under unloaded conditions, the conventional patch antenna array resonates at IEEE 802.16a 5.8 GHz Wi-MAX band with gain of 4.31 dBi and bandwidth of 425 MHz, whereas when each patch of this array is loaded with a metamaterial superstrate, composed with the pair of circular split ring resonators and wire strips, gain and bandwidth approaches to 11.9 dBi and 685 MHz, respectively, which corresponds to gain improvement by 7.6 dBi and bandwidth enhancement of 260 MHz. The proposed antenna is fabricated and tested to compare simulated and measured results. A good compliance is observed between these two results. Equivalent circuit model of the composite structure has been developed and analyzed.

“…Introducing patch antenna design for radar application is in recent trend of research. Low weight high efficiency radar for L, S, and C band is developed in [2], C and K band reflector array in [3].Similar design is presented [4][5][6] for radars at lower frequency bands. X band is very prominent band for radar application like Anti-collision, Automatic Turret Control, Fire Control, Surveillance, Perimeter Surveillance [7].…”

This paper presents a simulated design of high performance elliptical ring Microstrip patch antenna at resonant frequency of 8 GHz for radar. Owing to its intrinsic geometry elliptical ring patch is found to be suitable candidate for designing high power, large gain and better efficiency conformal antennas for radar at X-band or even higher frequencies. Simulated antenna shows very high average gain of 7.5 dB for entire bandwidth of 340MHz i.e. 4.25% impedance bandwidth. Simulated results shows very good return loss performance, S11 parameter is-42.5 dB at resonant frequency. Roger Ultralam 2000 substrate is used to design the antenna. Average radiation efficiency of antenna is very high (97.9%). Design show great promise for radar application with no side lobes, high directivity of 7.71 dB at 8 GHz & very high front to back ratio. Comparative study of recent works in X-Band and our design is presented & variation of return loss with dielectric height is also elaborated in paper.
