A low‐profile, high gain Fabry‐Perot Resonator antenna with a wide operation bandwidth (BW) is presented in this paper. The proposed design consists of an ellipse‐shaped dipole as a wideband radiating source, which is reflected by an artificial magnetic conductor ground plane to achieve low‐profile structure. The antenna gain can be significantly enhanced by the use of a half‐wavelength‐thick dielectric slab as a partial reflecting surface. Additionally, this dielectric slab also contributes to improving the radiation pattern characteristics of the proposed design, especially in the high frequency region. A final prototype with an overall size of 1.2λ L × 1.2λ L × 0.4λ L (λ L is free‐space wavelength at the lowest frequency of 3‐dB gain BW) has been fabricated to validate the concept. The measured results show that the proposed antenna yielded a wide 3‐dB gain BW of approximately 50.3% with a peak gain of 14 dBi and impedance matching BW of 48.9%.

“…Previously, several techniques have been widely used for enhancing the antennas gain with a unidirectional radiation pattern, such as frequency selective surface (FSS) and artificial magnetic conductor (AMC). [18][19][20][21][22][23][24] The AMC reflects normal incident waves introducing a zero degree reflection phase shift upon resonance. The 0 phase reflection bandwidth of the AMC lies in the range between +90 and -90 .…”

An ultra-wideband antenna is suggested, simulated, and fabricated for ground penetrating radar (GPR) and landmine detection applications. The reported design has wideband, high gain, and high directivity. The new configuration achieves unidirectional radiation characteristics maintaining circularly polarized (CP) radiation characteristics. The whole configuration is optimized using the particle swarm optimization algorithm to achieve the optimal bandwidth, gain, and axial ratio (AR). The performance of the overall geometrical design is analyzed in terms of bandwidth, gain, directivity, and AR. The proposed antenna offers a gain of 2.66 dB in free space, which is enhanced to 8.86 by using an artificial magnetic conductor. The measured results show that the proposed configuration offers −10 dB return loss bandwidth of 540 MHz over the frequency range (0.8-1.34 GHz) with~50.5% operational bandwidth and 3-dB AR bandwidth of 295 MHz for the frequency range (0.97-1.265 GHz) with an approximate percentage of 26.4%. Furthermore, the maximum gain over the CP-operated bandwidth close to 8.86 dB, at frequency 1.05 GHz, is obtained. It is anticipated that this antenna is suitable for GPR applications as well as for employment in landmine detection.

This paper presents a compact high-isolation dual-polarized dipole antenna with an artificial magnetic conductor (AMC) reflector. The proposed antenna is composed of a radiating element, two short pins and a 7 × 7 AMC array. By introducing two short pins, the port isolation is lower than −33 dB in the whole band on two ports. With the ring and AMC reflector, the dimension of the proposed antenna is only 0.36λ 0 × 0.36λ 0 × 0.16λ 0 at 2.2 GHz. The antenna also achieves a 10-dB return loss bandwidth from 1.6 to 2.78 GHz (54%) for both ports. The gain of the proposed antenna is around 8 dBi, and the cross-polarization is about 30 dB. Due to these properties, the proposed antenna can be applied to 2G/3G/long term evolution (LTE) base station and WLAN/WiMAX applications.
