TL;DR: Analysis of Multiband Corporate fed Bowtie Antenna Array having tuned in L Band shows that proposed antenna using Roggers RT/Duroid matarial is tuned at frequencies 1.05 GHz, 1.63GHz, 2.25GHz and 2.92GHz and provides 40.95%, 18.40%, 14.66% and 17.97% bandwidth respectively.
Abstract: This paper presents analysis of Multiband Corporate fed Bowtie Antenna Array having tuned in L Band. Bandwidth performance is analyzed for different substrate materials and effect of ground plane is presented. Simulation result shows that proposed antenna using Roggers RT/Duroid matarial is tuned at frequencies 1.05 GHz, 1.63GHz, 2.25GHz and 2.92GHz and provides 40.95%, 18.40%, 14.66% and 17.97% bandwidth respectively. Proposed antenna can be used for applications such as WCDMA, Mobile Satellite services, point to point, TV pickup and subscriber radio system (SRS). The antenna is simulated on HFSS virtual tool.

TL;DR: In this article, the reflection-type tunable band pass filter (BPF) was proposed for the L band, which is composed of two identical MEMS tunable BRFs, which are connected to a 90-degree hybrid circuit.
Abstract: This paper proposes the reflection-type tunable band pass filter (BPF) for the L band. The filter is composed of two identical MEMS tunable BRFs, which are connected to a 90-degree hybrid circuit. The trial fabrication validates the configuration by showing the low loss in seven bands from 0.8 GHz to 2.4 GHz.

Abstract: This paper describes a compact Ortho Mode Transducer (OMT) design and implementation for L-band. Symmetric orthogonal polarizations in common port were isolated in other ports into single linear polarization. This system is implemented to operate S -band that can be used in applications for satellite technology. A flared waveguide section is often used to couple the symmetrical radio recurrence signal to a normal port. An optimized OMT handles the recurrence band of 1.9 GHz–2.1 GHz for direct port and integrated port. It is often intended to produce good scattering outcomes with computation techniques. The coefficients of reflection of each port across the L- band (1.9-2.1 GHz) is less than −10 dB. An enacted architecture has port-to-port isolation throughout the intended S-band better than 30 dB and the quantified insertion loss is around 0.4 dB across the optimal level frequencies. The CST tool was used for the optimization and simulation of OMT. The device is designed to accommodate satellite systems feed chain specifications for antenna.
