Novel designs of miniaturized multi‐band 1 × 2 patch antenna array with electromagnetic band gap (EBG) for wideband operation are presented in this article. The proposed patch array is composed of three unequal arms fed by CPW‐to‐slotline transitions to widen the impedance bandwidth with multiple resonances. By adding two conventional mushroom‐type EBG (CMT‐EBG) structures on both sides of 100 Ω slotline transitions, the compact wideband patch array (first design) is obtained. This proposed design with CMT‐EBG includes two bands with the measured ranges (S11 ≤ −10 dB) of 6.65‐6.95 GHz (C‐band) and 8.57‐11.53 GHz (X‐band). Moreover, the proposed 1 × 2 patch array with the 3 × 3 CMT‐EBG array on the one side of the structure (second design) operates at multi‐bands with the measured −10 dB impedance bandwidths of 5.80‐5.98 GHz, 6.25‐6.47 GHz, and 8.48‐11.52 GHz. The second design compared to the first design introduces a considerable size reduction with more resonance tuning capability. The performance of the proposed designs is analyzed based on the EBG band gap properties near the slotline transitions. These designs with the EBGs indicate prominent features like resonance tuning capability, acceptable miniaturization, and enhanced impedance bandwidth with low‐fabrication cost. In this study, an equivalent circuit model of the proposed first design with EBG is also offered to describe the properties of multi‐band operation.

In this paper, a novel wideband microstrip-fed quasi-Yagi antenna is presented. The proposed quasi-Yagi antenna consists of a microstrip-fed monopole, three radiating patches (two square patches and a rectangular patch), and three parasitic strip elements as the function of reflector. In order to achieve wide bandwidth, two parasitical patches are etched on both sides of the substrate. Furthermore, the stepped microstrip feeding line is adopted so as to get a good impedance matching. A fabricated prototype with the dimensions of 40 mm × 55.5 mm yields a directional far-field radiation pattern with no director, a −10 dB bandwidth (2.21-5.4 GHz) of 83.8% and a peak radiation gain of 4.17 dBi. Finally, the proposed antenna is analyzed, fabricated and measured. Measured and simulated results are in good agreement.

In this paper, a novel design of compact 1 × 4 patch antenna array using electromagnetic band gap (EBG) for wideband operation is introduced. Three unequal arms fed by CPW‐to‐slotline through a coupling system of 100 Ω T‐shaped slotline transitions are utilized for broadening the impedance bandwidth with multiple resonances. By adding two conventional mushroom‐type EBG (CMT‐EBG) structures on both sides of 100 Ω slotline transitions, dual wideband patch array is obtained. The proposed 1 × 4 patch array with CMT‐EBG includes two bands with the measured ranges (S11≤−10 dB) of 6.71–6.97 GHz and 8.60–11.51 GHz. Moreover, more size reduction is achieved by using an edge‐shorted mushroom‐type EBG (ESM‐EBG) for the proposed array. This design with the ESM‐EBG indicates almost 37% size reduction compared with the proposed array without EBG. In this paper, an equivalent circuit model of the proposed 1 × 4 array with EBG is also introduced to describe the process of its bandwidth enhancement. © 2016 Wiley Periodicals, Inc.
