“…Compared with the uniform FPC antenna with a similar large aperture size in [14], our non-uniform design achieves a higher gain and aperture efficiency, which verifies the superiority of the proposed non-uniform method. In [25], a non-uniform FPC antenna with an aperture size of 100λ 2 0 is presented to achieve an extremely high simulation gain.…”

“…A trade-off between the radiation efficiency and the aperture illumination efficiency should, therefore, be made to minimize the degradation of the antenna directivity. In [14], a uniform FPC antenna with simulated peak gain of 24.0 dBi and aperture efficiency of 51.2% is designed at 12.5 GHz by using the optimized reflection coefficient of FSS. To the best of our knowledge, however, the measured gains of the existing uniform FPC antenna prototypes hardly exceed 21dBi.…”

A design of high-gain Fabry-Perot cavity (FPC) antenna is presented with non-uniform frequency selective surface (FSS) superstrate and electromagnetic band gap (EBG) reflecting ground. The non-uniform FSS superstrate and EBG ground are utilized to flexibly control the attenuation constant α over a large antenna aperture while ensuring the resonance condition of the FPC. The uniformity of the amplitude of the aperture field is improved significantly while obtaining appropriate radiation efficiency. Therefore, the high gain and high aperture efficiency can be achieved within a desirable bandwidth. The theoretical gain estimation is conducted to prove the superiority of the proposed antenna over a referenced uniform one. A straight-forward design methodology is proposed based on the radial leaky-wave theory and the modified transverse equivalent network (TEN) model. The non-uniform high-gain FPC antenna with a diameter of 6.6λ 0 is designed at the frequency of 15 GHz. Simulated results show that a gain of 24.6 dBi with an aperture efficiency of 67.9% has been achieved. The measured gain is 24.0 dBi with an aperture efficiency of 58.4%. The 10dB return loss bandwidth and 3 dB gain bandwidth are 5.3% and 3.2%, respectively. The proposed antenna overcomes the limit on aperture efficiency and gain of conventional uniform FPC antennas, and the presented methodology can guide the design of two-dimensional non-uniform high-gain FPC antennas.INDEX TERMS Fabry-Perot cavity (FPC) antenna, frequency selective surface (FSS), high gain antenna, high aperture efficiency.

“…In the classical article that first proposed PRS antenna [10], its working principle and design parameters are all based on an intuitive ray-tracing model. In some subsequent designs of PRS antennas, the ray-tracing method has also been used to achieve faster optimization [27], higher gain [28], and arbitrary beam deflection angle [15]. In [15], ray-tracing is employed to derive the required phase distributions for a phase-modulated PRS to achieve a desired beam deflection angle.…”

<p> A reconfigurable partially reflective surface (PRS) antenna can offer low-cost and low-complexity beam steering, traditionally implemented using a phased array with a bulky feeding network. This paper utilizes ray-tracing to prove analytically that an inductive nonuniform PRS facilitates larger beam deflection and lower sidelobe level (SLL) than a capacitive one, given the same reflection phase difference. With a suitable tradeoff in the beam deflection angle and gain variation between the reconfigurable states, an inductive reconfigurable PRS is designed for a ±13° steering range. To enhance the steering range with minimal complexity, two parasitic elements loaded with PIN diodes are added to the feeding source, resulting in the overall steering range of ±30°. The fabricated prototype verified that the pencil-shape beam can be steered towards 0º and ±30º with SLLs of less than -19dB at 5.5GHz. The antenna achieved peak realized gains of 9.5-10.4dBi for the three states with gain variation of less than 0.9dBi. The measured overlapped impedance band covers 5.41-5.63 GHz for all states. </p>
