“…But microstrip antennas have a major disadvantage which is its low gain. Modern wireless communication system requires high gain omnidirectional antenna which can radiate omnidirectionally in azimuthal direction [2,3]. Due to low gain in conventional antenna it is not possible to cover the required region for wireless applications.…”

Abstract:In this paper a new complementary quad band omnidirectional planar microstrip antenna array has been proposed. This antenna consists of cascaded connection of three rectangular shaped patches on the upper side, two rectangular shaped patches on the ground side and one "I" shaped resonator at the ground to produce the effective structure of antenna array which can radiate omnidirectionally with high efficiency, moderate gain, low reflection and useful radiation pattern. This cascaded quad band antenna array operates at Bluetooth (2.35-2.53) GHz, WIMAX (3.25-3.50) GHz, HIPERLAN (4.06-4.30) GHz and WLAN (5.37-5.86) GHz with S 11 <-10 dB and stable radiation pattern having gain 2.8dBi, 3.32dBi, 3.49dbi,and 6.4dBi respectively. The bandwidth of these bands for proposed antenna becomes 180 MHz, 250 MHz, 240 MHz and 490 MHz respectively.

Abstract-This paper proposes and designs a new method of dualband omnidirectional planar microstrip antenna array. A cascade of transposed microstrip lines have been adapted to produce effective antenna structures that radiate omnidirectionally, with high efficiency, low reflection, and useful radiation patterns. In this paper, the antenna structure has been found to have low-pass characteristics due to the periodic discontinuities at the transposed junctions. The analysis and design of the low-pass characteristic are performed according to the filter theory of periodic structures and full-wave simulation. Therefore, a relatively higher frequency radiating array is appropriately designed with a low-pass filtering attribute, which prevents the lower frequency radiators from resonating at the relatively higher frequency. An air gap between adjacent transposed sections is proposed in order to enhance impedance matching, and a fork shape stub at the end is used as a virtual short point to enhance radiation at the higher frequency. Finally a single port dualband omnidirectional antenna array is obtained by locating the higher frequency radiating array with low-pass filtering attribute near the antenna feed and a relatively lower frequency radiating array at the end. An example of a dualband omnidirectional planar array is demonstrated experimentally, which operates at 2.32 ∼ 2.56 GHz and 5.65 ∼ 6.10 GHz with S 11 < −10 dB and a stable radiation pattern, and corresponding gains of 7.0 ∼ 7.6 dBi and 6.9 ∼ 7.9 dBi respectively.

“…However, these slot antennas mentioned above have larger dimension and are not good candidates for WLAN applications that require miniaturized antennas. Moreover, to adapt to various WLAN environments, a WLAN antenna should be capable of operating at dual frequency bands [5][6][7][8]. For instance, these frequency bands may cover 2.400-2.484 GHz (specified by IEEE 802.11b/g) and 5.150-5.350/5.725-5.825 GHz (specified by IEEE 802.11a).…”

Abstract-In this paper, a novel dual-band rectangular slot antenna for wireless local area network (WLAN) applications in IEEE 802.11b/g/a systems is presented. The proposed antenna, fed by a 50 Ω microstrip line, has size of 32 mm × 28 mm × 1.6 mm. By introducing a pair of U-shaped strips, the proposed antenna can generate two separate impedance bandwidths. The prototype of the proposed antenna has been successfully constructed and tested. The low-band resonant frequency is located at about 2.4 GHz, with −10 dB impedance bandwidth from about 2.3 to 2.5 GHz. The highband resonant frequency is located at about 5.7 GHz, with −10 dB impedance bandwidth from about 4.9 to 6.0 GHz. In addition, the measured results show good radiation characteristics at the two operating bands, proving the dual-band operation of the proposed antenna.
