“…In recent years, different designs of patch antennas for multi-frequency operation have been presented by many researchers. In [10], [11] proximity coupled feed technique was used for dual-band frequency operation, this technique was very difficult to design and manufacture for real-world antennas. A new compact antenna design has been presented for cellular and WLAN communications.…”

In this paper, a novel multi-frequency microstrip antenna with complementary ring slot resonator (CRSR) structure that satisfies Bluetooth, worldwide interoperability for microwave access (WiMAX), and wireless local area network (WLAN) applications is proposed. The conventional antenna consists of a circular microstrip patch at a resonance frequency band of 2.5 GHz. By loading two CRSR at the radiating element, three operating frequency bands 2.5 GHz, 3.6 GHz, and 5.2 GHz are achieved. The operational bands covered by the antenna are Bluetooth 2.5 GHz, WiMAX 3.6 GHz, and WLAN 5.2 GHz. The insertion of CRSR to patch antenna has made it possible to compact and simple design, and miniaturized antenna for cognitive radio. Moreover, the directivity of the proposed antenna is adequate with acceptable radiation properties and perfectly matches with the simulated and measured results.

Abstract:In this paper, a novel multiband patch antenna has been designed, simulated, and measured for GSM, DCS, IMT, WiMAX, and WLAN (IEEE 802.11 a/b/g/n) applications. The proposed antenna consists of a square patch and square-loop elements (connected through 50 Ω microstrip line) excited by a coaxial feed. With the help of square loop elements, the antenna is able to provide multiband response. The proposed antenna occupies an overall size of 80 × 80 × 1.6 mm 3 . The 10 dB bandwidth criterion offers good impedance bandwidth for desired bands. Moreover, gain of the proposed antenna is acceptable with good radiation properties. The proposed antenna is fabricated on FR-4 substrate and it is noted that the simulated and measured results are in good agreement.

This study presents the design of a low‐cost fractal antenna loaded with parasitic edge‐coupled (EC) split ring resonators (SRR). Parasitic EC SRR elements result in improved impedance matching leading to improved bandwidth. The basic resonant structure is a circular patch antenna designed at 3.2 GHz on low‐cost FR4 substrate with relative permittivity 4.4, and 1.6 mm thickness. A single iteration of circular patch and slots is used to make it fractal and in order to achieve multiband performance, the antenna is inset fed by a 50 Ω microstrip line. A prototype of the proposed antenna is fabricated and tested for results, a comparison between fractal antenna with and without SRRs is made and the results confirm that a better impedance matching is achieved in the later case, also a 3% increase in bandwidth is achieved at 8.5 GHz. A good agreement between simulated and measured results is obtained, an estimated gain of 13.3 dB is provided by the proposed antenna. The overall dimensions of the antenna are 45 mm × 45 mm and it may be used for wireless applications at 3, 5, 6.8, 7.5 and 8.5 GHz with an average bandwidth of 200 MHz.
