This paper proposes a single-feed, compact, metasurface-based antenna with circularly-polarized (CP) radiation for the Global Positioning System (GPS) receivers. The antenna consists of a square patch on the metasurface, which is a periodic lattice of 4 × 4 square metallic patches arranged on a grounded dielectric substrate. The CP radiation is obtained by truncating corners of the patch radiator...
This paper proposes a Ka-band aperture-coupled microstrip patch antenna (ACMPA) based on low temperature co-fired ceramic (LTCC) technology for circular polarization (CP) at 29 GHz. The antenna consists of an aperture coupled patch with stacked parasitic strips (SPS). The CP is produced by cutting the patch and the parasitic strips. The antenna provides an impedance bandwidth of 1.2 GHz from 28 GHz...
A new antenna design that uses two orthogonal feeds to excite circular polarization in a meshed patch antenna is presented. The antenna is designed on a transparent borosilicate glass substrate to be suitable for integration with solar panels on a microsatellite. Simulated performance shows that for a center frequency of 2.4GHz, an impedance bandwidth and axial ratio of of 50MHz and 0.68dB, can be...
In this paper, a novel method to enhance axial ratio bandwidth of circularly polarized (CP) patch antenna using artificial magnetic conductor (AMC) structures with LTCC technology at Ka-band is proposed. In order to improve the axial ratio bandwidth, the traditional PEC plane is replaced by an AMC plane. The AMC is composed of periodic square unit cells with truncated opposite corners. The AMC structure...
The performance of a circularly polarized microstrip patch antenna is improved using a circular mushroom-like substrate. The microstrip patch antenna is fed by a coaxial probe and is integrated within a circularly periodic structure to increase the antenna gain. The circular mushroom-like structure is a combination of two periodic structures with different periods. One is made of metallic rings and...
