A new compact printed antenna structure for multiple wideband applications

Abstract

This paper presents the design of a new compact antenna structure for multiple incorporating operation service. The proposed antenna is suitable to operate at three different frequency bands, (1.77GHz-2.67GHz), (3.1GHz- 4.58GHz), and (5.5GHz-6.5GHz) with a return loss less than -10dB. The antenna structure includes a CPW fed line, the technique used to enlarge the frequency bands is the slots technique and in the same time we have developed a new antenna structure which operates in various wireless communication applications. The antenna parameters have been investigated and optimized by using CST Microwave Studio. To validate the CST Microwave Studio results before the antenna achievement, we have conducted another study by using ADS. The final circuit was achieved, measured and validated. Experimental results show that the proposed antenna with compact size of 42*32.7 mm2 has good radiation characteristics and operating in specific microwave applications ISM band, WLAN, WIFI, WIMAX and RFID.
