“…The outer element has symmetrical truncations. For the top dual‐band element, both TM01 and TM03 are excited and circular polarisation is produced due to the truncations and slot arrangement [3, 5]. With proper adjustment of patch sizes, a wide frequency ratio is achieved.…”

“…Single‐layer single‐feed patch antennas for dual‐band circular polarisation were proposed by loading Y‐shaped or T‐shaped slots in a square patch [3] or coupled annular rings with asymmetric cross‐slots in the ground plane [4]. Furthermore, in [5], a single‐layer patch employing four slots and truncated corners was used to excite dual‐frequency dual‐sense circular polarisation. However, emerging multimode systems such as wireless fidelity (WiFi) and worldwide interoperability for microwave access (WiMax) demand circularly polarised antennas operating over more than two bands, which are widely disparate.…”

A triple-band circularly polarised microstrip patch antenna operating in the 2.4, 3.5 and 5.7 GHz bands is presented. The antenna consists of two substrate layers with an electromagnetically coupled low-band patch in the middle layer and a probe-fed dual-band patch on the top layer. The impedance bandwidths (voltage standing wave ratio (VSWR) < 2.5) for the three frequency bands are 112, 118 and 427 MHz with 3 dB axial-ratio bandwidths of 15, 44 and 36 MHz, respectively. The peak gains across the operating bands are 4.2, 5.5 and 4 dBic, respectively.

A compact circularly polarized (CP) patch antenna is presented for modern communication systems. The prospective antenna consists of a microstrip-line inset-fed rectangular patch and a defected ground plane. A rotated rectangular slot and a modified electric-inductive-capacitive (m-ELC) resonator are introduced in the patch and the ground plane to achieve multiband behaviour. A corner of the radiating patch is truncated and an arrow-shaped stub is introduced for generating circular polarization. The physical area of the substrate is 0.26λ0 × 0.22λ0, and the radiator size is 0.16λ0 × 0.14λ0, where λ0 is the free-space wavelength estimated at the lowest frequency. The measured (S11≤-10 dB) bandwidths of the antenna are 80 MHz (3.58%) at 2.23 GHz, 75 MHz (2.64%) at 2.84 GHz, 80 MHz (2.50%) at 3.19 GHz, and 70 MHz (1.82%) at 3.83 GHz. The measured 3-dB axial ratio bandwidths are 40 MHz (1.41%), 100 MHz (3.12%), and 60 MHz (1.57%) at 2.84, 3.20 and 3.82 GHz, respectively. The proposed planar antenna design does not need dual-feed or multi-layered patches for achieving multiple CP bands. It offers easy integration with the printed circuits of the communication systems.

“…This solution is interesting but the thickness of the antenna is generally large [3]. The second technique, used in this article, consists in using a square patch on a single substrate layer, having rectangular slots etched in the metallization of the radiating element to produce dual‐band operation [4–6]. The technique uses in this kind of structure, presented in Ref.…”

In this article, we present a low‐profile and low cost antenna for GPS (L1–L2–L5), Galileo (E5–E1–E2), and Glonass (G1–G2) standard. This antenna is a dual‐feed planar patch antenna with four slots to achieve dual‐band operation. The radiating element is fed by a wideband 90° quadrature hybrid coupler to obtain circular polarization on the both bands. The quadrature feeding is achieved using a three‐branch‐line hybrid coupler. The return loss bandwidth of the system (S11 ≤ −10 dB) is 22% in the lower band and 14% in the upper one. The axial ratio (AR) bandwidth in broadside direction (AR= 3 dB) is 20% in the lower band and 11.3% at the upper one. The antenna gain is 6 and 8.4 dBi in the normal direction at the central frequency of 1.23 and 1.6 GHz, respectively. The total dimensions of the antenna are 170 mm2 with a thickness of 7.524 mm. © 2012 Wiley Periodicals, Inc.
