A microstrip compact size second order bandpass filter for wireless applications is presented. The band pass filter is based on Composite Right/Left handed transmission line. The two resonators are designed using only one composite right left handed unit cell. The bandpass filter has the advantage of compactness (its size is only 2.3 X 2.3 cm 2 ). A second order band pass filter with centre frequency of 4.77GHZ is designed, simulated and measured. The filter has bandwidth of 200MHz and insertion loss lower than 1.8 dB is achieved within pass band. A good agreement between simulated and measured result was achieved.

The design and analysis of meta-material inspired loaded monopole antenna for multiband operation are reported. The proposed antenna consists of multi resonators inspired from half mode composite right/left handed cells, which has a simple structure, compact size, and provides multiband functionalities. As a proof of concept, a triple band antenna covering all possible WiMAX operating bands, has been designed, fabricated, and characterized. The hosting monopole patch itself generates resonance for 3.3–3.8 GHz band, whereas the loaded metamaterial cells add extra resonance frequencies. The loading of two resonator cells introduces two extra resonances for 2.5–2.7 GHz and 5.3–5.9 GHz bands, respectively. The antenna's operating principle and design procedures with the aid of electromagnetic full wave simulation and experimental measurements are presented. The antenna has good omnidirectional patterns at all three bands. The monopole patch size is 13.5 × 6.5 mm2and the whole antenna size (including the feed line) is 35 × 32 mm2. Compared with conventional single band microstrip patch radiator, the radiator size of this antenna is only 8.5% at 2.5 GHz, 17% at 3.5 GHz, and 37% at 5.5 GHz.

“…One of the novel properties of the CRLH TL is its zeroth order mode which enables the design of ultra-compact microwave devices. Examples for these components include resonators [6], filters [7], phase shifter [8] and antennas [9][10][11][12][13].…”

This paper presents a zeroth order metamaterial substrate integrated waveguide antenna. The antenna is designed to have a compact size based on employing only one composite right/lefthanded cell. The antenna resonates at 6.1 GHz with overall radiator size of 14.4 mm × 8 mm which represents 50% size reduction compared to conventional microstrip patch antenna that operates at the same frequency. The zeroth order mode of the antenna has been verified using analytical explanation and full wave simulations. Moreover, the full wave simulations and experimental measurements have been employed to confirm the antenna matching properties and radiation characteristics.
