“…Proper design of the antenna, as one of the key components of the whole system, plays an important role to make the system efficient in terms of its performance, lightness and compactness. The multiband antennas are good candidates for using in modern wireless links which operate at several frequency bands [1][2][3][4]. Among multiband antennas the monopole structures have attracted a great deal of attention.…”

Abstract-In this paper, a modified version of the multi-band multiple ring monopole antenna is proposed. The height of the new design which consists of multiple half rings is half of the original one. The modified design is more attractive for low profile applications due to its lower height. The antenna is simulated and measured. It is shown that the simulation and measurement results are in good agreement. The performance of the modified version of the antenna is compared with the original design in terms of input characteristic and far field radiation patterns. It is shown that the multiband behaviour of the modified design is similar to the original one. However, there is a frequency shift between the operating bands of the new and the original antennas. The radiation patterns of the both antennas are similar to the conventional monopole antenna in lower operating frequency bands. However, degradation in radiation patterns of the both antennas is observed as frequency increases.Corresponding author: A. Mirkamali (ali mirkamali@znu.ac.ir). 174Mirkamali et al.

“…Several types of antennas, such as log-periodic [1] and reflector antennas [2], are limited by their large dimensions for these applications. Microstrip patch antenna can provide unidirectional patterns and has major advantages of low profile, low cost, light weight and easy fabrication [3][4][5][6][7][8], but its impedance BW is not wide enough at the condition of stable unidirectional radiation patterns.…”

Abstract-A wideband unidirectional antenna composed of a magneto-electric dipole with Γ-shaped feed is designed. Simulated and measured results are presented. It achieves an impedance bandwidth of 84% for VSWR ≤ 2 ranging from 2.05 GHz to 5.05 GHz, stable peak gain of around 5 dBi, unidirectional radiation patterns and low cross polarization over the whole operating band. It is sufficient for accommodating recent wireless communication services such as 3G, WiFi, WiMax, Bluetooth, WLAN and Zigbee, etc.

“…Dual-band dual-sense CP antennas have become a popular study in this research area during the last few years. Several dual-frequency designs for antenna structures have been proposed in [1][2][3][4][5][6][7][8][9][10][11], including slot antenna, notched printed monopole antenna, multifunction hybrid antenna, dual-feed antenna arrays.…”

Abstract-A single-feed dual-band dual-sense circularly polarized (CP) microstrip antenna is proposed. The antenna consists of a circular radiating patch with a ring slot, two substrates with an air layer sandwiched between them and a capacitive coupling feed. The two resonant frequencies are controlled by the size of the circular radiating patch and the ring slot. By introducing the perturbation, the fundamental resonant mode splits into two orthogonal degenerate modes, and the CP radiation pattern is obtained. Capacitive disk coupling feed is also used in the design to enhance the bandwidth. The key parameters of the design are investigated to show how to obtain dual-band and dual-sense CP. The proposed antenna prototype is fabricated and measured, and experimental results show that good CP radiation performances are obtained at both resonant frequencies.
