In this paper, a circularly polarized antenna is proposed for satellite communication system. Commercially available Finite Integration Technique (FIT) based software Computer Simulation Technology (CST) microwave studio and finite element method solver based High Frequency Structural Simulator (HFSS) have been used in this analysis. The proposed antenna achieved 3dB axial ratio of 30 MHz with −10dB...
A circularly polarised (CP) wideband hook-shaped microstrip fed patch antenna is presented. The wideband CP property for the proposed antenna is achieved by the hook-shaped branch in the ground plane and inverted asymmetric arm L-shaped microstrip fed. With an optimised dimension of the proposed antenna parameter, the experimental results show that the antenna has a 10 dB impedance bandwidth of 1...
This paper presents a new wideband RFID reader antenna for UHF application. By applying log periodic antenna theory, the proposed antenna is achieved by employing three loop wire elements and fed by a pair of crisscross feed line. The proposed antenna exhibits wide bandwidth of 25.2 % operating frequency at UHF band from 811 MHz to 1046 MHz. The return loss and radiation pattern of the proposed antenna...
A novel dual band antenna for Wireless Local Area Network (WLAN) applications is presented. The dual band characteristic is achieved by feeding two different length resonant paths with a 50 Ω microstrip line. The compact antenna only occupies 5.3 × 16 mm2 and promotes wideband characteristic. The bandwidth for lower resonance spans from 2.03 GHz to 2.80 GHz (30.3%) and 4.86 GHz to 6.44 GHz (31.6%)...
Macro diversity handover (MDHO) is the process by which the mobile station (MS) communicates with two or more access stations. The list of the access stations is called a diversity set. In this paper, we investigate the performance of an enhanced MDHO technique for TDD-OFDMA-based interference-limited multi-hop relay cellular networks. The enhanced MDHO exploits all the data signals transmitted by...
