“…This process has gained popularity since its inception for use with microcoaxial lines [27], [28]; however, its versatility and small feature size makes it ideal for use with waveguide above W-band. The structural material is copper, which is grown after a photoresist is deposited to define the waveguide walls.…”

This paper describes frequency scanning slot arrays operating from 130 to 180 GHz. The arrays are micro-fabricated using the PolyStrata sequential copper deposition process. Measured reflection coefficient and radiation patterns agree with HFSS full-wave simulations. The voltage standing wave ratio is less than 1.75:1 over the entire frequency range, and the measured scanning is 1.04 GHz from 130 to 150 GHz and 32.5 over the full frequency range. The measured gain is 15.5 dBi for a 10-element array at 150 GHz and 18.9 dBi for a 20-element array at 150 GHz with about 3 dB of variation over the scan range.Index Terms-Beam steering, g-band, linear antenna arrays, millimeter wave radar.

“…However, studies on planar LP antennas are mostly limited to microwave frequencies [1][2][3][4]. Even though a two-arm planar LP that operates up to 110GHz is reported in [5], dual polarizations are not supported and sequential surface micromachining is required for fabrication, which can increase the prototyping cost significantly, particularly when compared with the traditional printed circuit board (PCB) manufacturing. This paper demonstrates an 18GHz to 40GHz dualcircularly polarized four-arm planar LP antenna with monolithically integrated quadrature hybrid.…”

“…LP antennas are widely used in varieties of wideband communication systems due to their frequency independent characteristic [2][3][4]. It has been shown that by using the recently developed surface micro-fabrication process, bandwidths in the excess of a decade are achievable with planar two-arm LP antennas [5]. In modern millimeter-wave (MMW) electronic warfare systems, wideband dual polarized antennas are typically desired [6][7], of which a four-arm planar LP is an excellent candidate for receiving only platforms.…”

This paper demonstrates an 18-40GHz four-arm planar log-periodic antenna with integrated wideband hybrid fabricated using printed circuit board (PCB) process. The two orthogonal linear polarizations are obtained by exciting the logperiodic structure with two microstrip lines perpendicularly oriented in two PCB layers. Two circular polarizations are obtained by monolithically integrating a quadrature hybrid with the antenna. The antenna with hybrid achieves return loss greater than 11dB, gain around 3dBi, and good radiation pattern consistency throughout the bandwidth.

Technological advantages in solar activities particularly in solar radio burst (type I, II, III, IV, V) in radio region have created a demand of designing and constructing of Log Periodic Dipole Antenna (LPDA) to monitor. LPDA also plays an important role in modern communication systems such as TV, radar etc. The lengths and spacing of the elements of a LPDA are increases logarithmically from one end to the other. This paper presents the types of LPDA, mathematical equations required to design, flow-chart, MATLAB (MATRIX LABORATORY) code to obtain the antenna parameters and structure dimensions of the antenna elements to construct and the details of constructed LPDA of frequency range of 160MHz to 1900MHz with 24 elements. MATLAB tools and built-in math functions enables to explore multiple approaches and reach a solution faster than traditional programming languages, such as C/C++ or Java. It provides a good accuracy to calculate LPDA structure parameters required for LPDA design.
