A novel square ring printed antenna has been suggested for dual‐band circular polarization (CP). The geometry contains a square patch and a square ring structure for dual‐band operation. Circular polarization is achieved using triangular cut at the boundary and right angle bend with inner perturbation. The suggested antenna is excited from the lower layer through electromagnetic (EM) coupling technique. The antenna shows good impedance bandwidths of 90 MHz (2.43‐2.52 GHz) and 800 MHz (5.7‐6.5 GHz, respectively. The antenna shows 3 dB axial ratio bandwidth of 20 MHz at lower band and 120 MHz at upper band with improved gain > 6 dBi. The simulated and measured results are well agreed with each other. The antenna is promising wideband operation at the upper band. This antenna was implemented on fiberglass reinforcement laminated Arlon substrate with dielectric constant (ɛr = 2.55), and the overall physical dimension of 30 × 30 × 3.048 mm3. The designed antenna can be extensibly applicable in WLAN/Wi‐MAX communication. The presented antenna is designed using hyperlynx IE3D and the simulated results are presented.

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.

A dual mode square-ring defected ground waveguide (SR-DGW) with defected square patch is first proposed to excite a single-feed dual mode circularly polarized (CP) patch antenna, which can improve the impedance bandwidth and achieve the CP radiation pattern. The defected square patch is called the perturbation element. By optimizing the size of the perturbation, the degenerate modes of the dual mode SR-DGW are split and their orthogonal modes can be excited simultaneously. Due to the dual mode of the SR-DGW, the TM 01 mode, and TM 10 mode of the square patch antenna are excited simultaneously, which can improve the impedance bandwidth of the antenna. Meanwhile, owing to the orthogonal modes, CP radiation pattern of the antenna is obtained. Then, for a better impedance matching, an L-shaped spurline embedded in the feedline is introduced. The simulated and measured results show a good performance of the proposed antenna. The measured −10 dB impedance bandwidth is 10.4% (3.56 GHz-3.95 GHz). The measured 3 dB axial ratio bandwidth is 5.36% (3.63 GHz-3.83 GHz). Detailed designs and experiments are described and discussed.
