Compact arc‐shaped antenna with binomial curved conductor‐backed plane for multiband wireless applications

Abstract

This study proposes a novel design of compact printed multiband monopole antenna with binomial curved conductor‐backed plane which generates five wide resonant frequency bands for |S11| ≤ −10 dB to cover 2.4/5.2/5.8 GHz wireless local area network, 2.5/3.5/5.5 GHz worldwide interoperability for microwave access and ultra‐wideband applications simultaneously. The radiating elements of the monopole are composed of multiple arc‐shaped strips. The radius of each arc‐shaped strip varies proportionally to the arithmetic progression sequence. The proposed multiband antenna is studied with different shapes of conductor‐backed plane through the variation in order N of binomial curve equation. The overall dimension of the proposed multiband antenna is 32 × 25 × 0.8 mm3. The prototypes of the proposed multiband antenna are fabricated and tested. The radiation mechanism of the proposed multiband antenna is explained using simulated current distributions. Simulated and experimental results obtained for these antennas show that they exhibit good radiation behaviour within the operational frequency bands.

Compact triple-band stacked monopole antenna for USB dongle applications

“…Because of advantages of low profile and scope of easy way of fabrication, printed monopole antennas are widely used to operate in multiple bands. As a result, many such monopole antennas were designed for WLAN/WiMAX applications . To get multiple bands, different types of radiating strips are used in the patch, while parasitic elements in Refs and grounded stub in Ref are used in addition to monopole elements.…”

A novel design of multiband printed anchor‐shaped slot antenna

“…Recently, lots of multiband antennas have been reported for WLAN/WiMAX applications. In most cases, the planar monopole antenna and microstrip‐fed patch (or slot) antenna are preferred to obtain multiband characteristic and employed as internal antennas for WLAN/WiMAX applications . In Ref.…”
