“…The main advantages of CCHA are their improved radiation efficiency compared to a traditional horn antenna, increased directivity, better pattern control, improved impedance matching, and low side-lobe and cross-polarization levels [14,15]. These features make CCHA an ideal choice for outdoor applications where other types of antennas may not be suitable [17][18][19].…”

The far-field gain of commercial horn antennas primarily depends on aperture area and flare length. Traditionally, for every dBi of gain increment, the flare length should increase by 20% and the aperture area by 10%. External lens classes, such as gradient refractive index, concave, or Fresnel, are used to improve gain by ≤ 2 dBi, but at the cost of a volumetric increase by 75% in the range of 4.8-6 GHz. We propose a hollow dielectric loading (HDL) loaded in the flare section of the horn antenna. The shape and position of the HDL are optimized using an evolutionary algorithm to obtain the maximum gain from a conical corrugated horn antenna (CCHA) at boresight. The optimized design yielded a total volume 40% smaller than traditional horn while achieving 3.5 dBi peak gain improvement in the operating frequency range. We also observed an improvement in the electric field by 24% while retaining parity in the impedance bandwidth. A 3D-printed prototype of the optimized CCHA and the HDL is fabricated and measured. The measured and simulated results demonstrated good agreement with a maximum difference of 4%.

“…An antenna with flare geometry is optimised to match the impedance properly with the lower main lobe ripple in 1.4-11 GHz frequency range [2]. Various other shapes of the pyramidal horn antennas are designed to obtain constant beamwidth behaviour [3], to generate higher order modes [4,5] and cross-polarisation reduction [6,7]. An improved version of the double-ridged guided horn (DRGH) [8] with dimensions identical to traditional DRGH [9] which suffers from pattern deterioration is designed having better VSWR performance at higher frequencies.…”

A parabolic profile pyramidal horn antenna with flaring in both the E‐ and H‐plane is presented in this study. The proposed structure having aperture dimensions of 518.10 × 408.36 mm2 is designed and fabricated for S‐band (2.2–3.3 GHz). Due to increase in the flaring by 3.35° in the E‐plane and 3.18° in the H‐ plane compared to the optimal typical pyramidal horn antenna (TPHA), a half‐power beamwidth (HPBW) of less than 16.20° in both the planes with higher gain is achieved in the proposed antenna. The maximum phase centre (PC) variation, phase and amplitude variation of the electric field across the aperture in the proposed design are half compared to TPHA throughout the band, thus having good PC stability and lower phase error. The cross‐polarisation level and the measured return loss of <25 and 15 dB, respectively, is achieved throughout the band, thus providing a good impedance matching and single dominant mode of propagation, i.e. TE10. With the lower HPBW and higher gain, the proposed antenna can be used in applications where point directive beam is required such as wireless power transfer to charge sensors and batteries of quad‐copter and so on.

“…The antenna radiating tilted beam has been widely used in many applications such as satellite communications, radars, and global navigation satellite systems due to its advantages such as light weight, low cost, and simplicity in fabrication . However, traditional methods for tilted beam, such as radiation pattern synthesis, wave beamforming, and array antenna techniques , mainly include two steps‐antenna cell design and beam algorithm application.…”

A miniaturized broadband circularly polarized antenna with tilted beam is designed and fabricated using the complementary split ring resonator (CSRR) splits and flower-spiral (FS) structure. This antenna is composed of a FS structure, helix feed line, and ground plane loaded five CSRR splits. The voltage standing wave ratio is improved through the FS structure based on the Archimedean spiral arm. And the axial ratio is improved due to the five CSRR splits and FS structure. Simulated and measured results both confirm that the ground plane is reduced about 75.2% and the bandwidth significantly broadened from about 10.5% to about 27.6%. Experimental data show a reasonably good agreement between the simulation and measured results.ABSTRACT: A wide locking range and low phase noise injectionlocked frequency divider has been developed by CMOS 0.13-lm technology. The proposed differential complementary injection-locked frequency divider (CILFD) consists of five-stage complementary inverter type connection. The differential input and output are implemented using auxiliary cross-coupled inverters. The measurement results show a divide-by-5 division ratio and a locking range from 1.5 to 4.5 GHz with an input power lower than 25 dBm. The power consumption of CILFD is 1.0 mA from 1.4-V power supply when it locked at 3-GHz input signal.
