Abstract
The rapid growth in wireless communications of today’s era requires a new generation of antennas whose operating frequency range is greater than the FCC allocated UWB (3.1-10 GHz) frequency range and also operate simultaneously for multiple communication standards in single band of frequency. Microstrip antennas technology provides these features. A ubiquitous compact asymmetrical triangle truncated polygon structure monopole fed super wideband microstrip antenna for wireless communication is proposed in this paper. The antenna uses a compact size of 50X40 mm.2 The irregular tapered truncations on patch geometry have potential effects on enlargement of operating frequency band. The antenna is designed using modified epoxy substrate material of ε= 4.2, h=1.6 mm at 3 GHz, fabricated and measured. The measured results confirm that the antenna has operating frequency band of 1.2-20.03 GHz (177.39%) with bandwidth ratio of 16:1. The antenna has stable radiation patterns and consistent gain over operating band. The time domain group delay of antenna is within 4 ns, which indicates good linear phase response. Furthermore, this proposed antenna is able to cover the DVB-H in L-band for PMP (1.45-1.49 GHz), DCS, PCS, UMTS, Bluetooth, WiMAX2500, LTE2600 and UWB bands applications.
